Skewed Polls: Proof of a Vast Left-wing Conspiracy?

In the months leading up to the 2012 presidential election, virtually every major poll has had President Barack Obama leading over Republican challenger Mitt Romney.

However, critics contend the polls have a built-in bias intended to boost Obama’s numbers.

At issue is the number of Democrats sampled for polls compared to Republicans. In many major polls, a significantly higher number of self-reported Democrats are surveyed.

Some Republicans say this skews the polls in favor of Obama while those supporting the polling methodology argue it simply reflects the reality of a larger Democratic voting base.

‘Skewed’ Polls Cause Concern

A review of polls by major firms reveals that virtually all survey more Democrats than Republicans. Almost all of these polls also show Obama leading by slim margins; margins conservatives say wouldn’t exist if pollsters surveyed equal numbers of Republicans and Democrats.

Take, for example, the latest United Technologies/National Journal Congressional Connection Poll. Among likely voters, the poll found the Obama/Biden ticket gets 50 percent of the vote compared to 45 percent for Romney/Ryan.

However, Democrats also outnumbered Republicans in terms of those surveyed. Of the likely voters polled for the Congressional Connection Poll, 36 percent identified themselves as Democrats compared to 28 percent who said they were Republicans.

The Congressional Connection Poll isn’t alone in this practice. According to, a poll tracking site operated by conservative QStarNews , virtually all recent major polls have used models that survey larger percentages of Democrats:

  • ABC News/Washington Post: +7 D
  • IBD/TIPP: +7 D
  • CBS News/NY Times: +5 D
  • Rasmussen: +3 D

Presidential Poll Weighting

Those supporting the polls say the numbers simply reflect the fact more Democrats are expected to vote in the upcoming election than Republicans. Many point to the 2008 election as support for this assumption. In 2008, exit polling from key swing states showed Democrats turned out in significantly higher numbers. For example, in Ohio, 39 percent of voters were Democrats compared to 31 percent who were Republicans.

In addition, many polls track trends among registered voters, and have found that Democrats and Independents have made significant inroads in increasing their registered numbers in recent years. A 2009 analysis of voter registration statistics found the number of Democrats registering to vote increased significantly compared to Republicans.

The data, compiled by researchers within the United States Election Project at George Mason University, found voter registrations among Democrats rose 10.8 percent from 2004-2008. Meanwhile, Republican registrations increased 0.5 percent during the same time frame.

Some point to this increase in voter registrations as a reason why more Democrats may be polled than Republicans.

    The heavy democrat skew of national polls has given all who crave a real change and love America cause for a broad smile.
    A close race is a Romney lead and eventual victory. I would like to add this thought from Leo Tolstoy:
    ” A man is a fraction whose numerator is what he is and whose denominator is what he thinks of himself. ”
    Imam hussien obama is 1 / 16 TRILLION

  2. Loyal2US says

    I saw too many emotional posts, upper case , etc, almost all from Romney supporters. Please, before your partisanship, you are a US citizen, a man. Just cool it down, it’s good for your health.

  3. says

    MI has no business of being a toss-up. A recent MI poll showed Romney in front of Obama by 1%.
    PA should be solid blue by now. Latest poll from Tribune showed Romney and Obama are tied at 47%.
    And OH is still within error of margin based on the latest Columbus Dispatch.
    President Obama will not be re-elected.
    In the end, Romney will get at least 277 electoral votes.

  4. Stanford Blue says

    If Romney wins it may very well set off civil unrest in every major urban area of this country. I am talking race riots like we have never seen before!

    If the polls surveyed an equal amount of Democrats and Republicans, they’d all end up in a 50-50 tie. You’re really grasping at straws here. It’s like you’re looking at a poll of kids that says kids overwhelmingly prefer candy to brussel sprouts and screaming like a lunatic that the poll sampled too many candy-lovers.

  7. java says

    The poll is random sample of the US population, why should the pollsters strive for a 50-50 split if that does not reflect the split in the population? Typical Republican twist of facts, I am sick and tired of it…

  8. Gregory says

    If the polls are done in a statistically random fashion, it should be an accurate (statistically) representation of the voters, at that time. Keep in mind that pollsters make their money by being accurate – and biased polls are not accurate. THE most important thing is that everyone go out and VOTE – you have no right to complain about the government in charge if you did not vote in the last election.

  9. bugbuster says

    The polls have historically been good but not perfect predictors of election results. What they can’t predict is what the campaigns will do or not do, and that is what makes the difference in a close election. Both these campaigns are on their A game. However, the numbers of Dems and Republicans isn’t as variable and unpredictable as that. There are more Democrats. Whether they can be got out to the polls in the right places to capture the electoral votes–that’s what will determine the result, and I don’t doubt that that is what is on the minds of the Obama campaign. I think that Romney could be a good President if the better aspects of his personality prevail, if he gets good advice, and if he follows it.

  10. jIM says

    Hey Enuf, it is unlikely that you are a moderate independent conservative. I ‘m gonna make a wild guess and say you are a far left liveral. And that you posted with that title to give your arguement more weight. How bout you leave planet liberal and come back to planet earth. BTW…Here is a very recent quote from Karl Rove :
    According to Rove, “There have been 31 national surveys in the previous seven days. Mr. Romney led in 19, President Obama in seven, and five were tied. Mr. Romney averaged 48.4%; Mr. Obama 47.2%.”
    “sometime after the cock crows on the morning of Nov. 7, Mitt Romney will be declared America’s 45th president. Let’s call it 51 percent-48 percent, with Mr. Romney carrying at least 279 Electoral College votes, probably more.”

  11. Joyce Edwards says

    In other words,there’s thothing wrong with the your own account, if there are more registered Dems., than more Dems. will get polled, thus showing a strongler allialiance to Obama. Obama wins. What’s strange about that. If you want to poll 50/50,Dems / Reb. that might be different,but we don’t have a 50/50 Demo/Reb. so what’s the point. You want to take an average of the population when you poll, not a controll.

  12. Robert says

    Early Voting Advantage = Obama – 62% to 38%.

    Ground Game Advantage = Obama.

    Latino Vote Advantage = Obama.

    Women’s Vote Advantage = Obama.

    Incumbency Advantage = Obama.

    Ahead in the polls = Obama.

    Way Ahead on the Prediction Sites = Obama.

    Money Advantage = Obama.

    Critical State Advantage = Obama.

    Caught in over 50 verified LIES = Romney.

    Caught Insulting the Middle Class with his smarmy 47% comment = Romney.

    Badly beaten in 2 out of 3 debates = Romney.

    Has not articulated a single plan = Romney.

    Climate Change LIAR = Romney.

    Good luck with that Republican criminals and lovers of LIES and Deceit!

  13. steve says

    This election will not be just a landslide but a real earthquake.
    Romney will be the VICTOR big time…
    Whoever wins g_d bless them !

  14. Loyal2US says

    I am supporting Ron Paul ,especially for his independence from Israel firster mindset.
    As two current candidates, R is more loyal to Israel.
    Conservative conspiracy is so ridiculous that not only pollsters made up poll, even labor statistics made up statistics, so whole world made up to against them. There is medical definition for this status, is it?

  15. says

    Polls sample more Democrats because there ARE more Democrats. It’s very simple. This complaint is no different than if someone on the left griped that polls are biased toward Romney because they don’t sample an even number of white people and black people. It’s an ignorant complaint, plain and simple.

  16. Nimunik says

    Hey Mike,

    Put down the koolaid! Mass wasn’t even close to the lowest unemployment from 2003 to 2007.
    You libs live on utruths!

  17. walt says

    An article that does little beside hand-wave towards claims by from the paranoid right, without full diagnosis, doesn’t accomplish much. The article leaves out any view on this issue from the left, and even worse, any of the deep discussion of statistical analysis that’s been published elsewhere. Far more self-identified independent voters are former Republicans than former Democrats. Those independent voters, in most states, favor Obama. Since Obama’s stand is more like the old Rockefeller Republicans than like the old Kennedy Democrats on most every issue, this makes a sense. To support Romney, you have to believe that telling lies at every opportunity is a leadership trait. To support the current Republican Party, you have to believe that the Confederacy should have won the Civil War. Neither of those is a traditional GOP stand.

  18. VIBHUTI says

    Yes of course it is left wing conspiracy:
    Lip less B ush senior raised taxes.
    Wonder Boy told the truth about weapons of mass destructions to start a war.
    It is left wing conspiracy if not billions millions were stolen in the name of war.
    It is left wing conspiracy rich get richer and but out the government.
    Of course it is left wing conspiracy that Romney does not which side of mouth he is speaking.
    Of couirse it is left wing conspiracy that we have elections every 4 years.

  19. Xander says

    For every cry of “bias!” from one side based a a certain factor, there is a countervailing one from the other side. Before Repbulicans get too comfortable and self-satisfied with the idea that polls are skewed against Republicans, just consider that almost 40% of households don’t have landlines anymore–just cell phones. Most of the polls out there don’t adequately capture the cell phone population. Now ask yourself, do you really think the type of people who get rid of their landlines are likely Republican voters? No need for name calling — just dig deep down in your heart and be honest with yourself.

  20. Guy Tuthill says

    First, “virtually every major poll has had President Barack Obama leading”? That’s a wildly inaccurate opening sentence. Romney polled ahead of Obama in the national popular vote more often than behind over the last month.

    Second, the point made by skeptical viewers is that the margin of Democrat weighting in 2012 is actually greater than the voting balance in the 2008 elections. That would indicate an enthusiasm level among Democrats greater than that of 2008, which seems awfully unlikely, given all the other indicators out there.

    Finally, the headline itself is sort of a scarecrow. Few call the weighting issue ‘proof’ of anything. It is usually simply discounted as suspect.

  21. Zero Hour says

    “Enuf says” says it all — the GOP has been hijacked by a bunch of whiners who are cheering on a draft dodger. It is so sad that the GOP blocked the veterans jobs and reintegration bill on Sept. 19th. When they start voting against our proud servicemen (who have lost life and limb) fighting fictitious wars– that’s when I stop voting for them.

  22. Steve says

    This post would be clearer, and less likely to be interpreted as biased, if it said “in a randomly chosen sample, most people self-identified as Democrats,” instead of saying “more Democrats were polled.” The latter formulation gives the incorrect impression that pollsters sought out Democrats to poll. That would not only produce a biased sample, it would be unprofessional and unethical. No one, however, is asserting this. The samples are indeed random. The problem is that a majority of random people self-identify as Democrats.

    The Republican SkewedPolls website you refer to–with no explanation of how it could be–declares the self-identification as incorrect. To “correct” the error, it assumes an “ideal” ratio, then weights the Republican votes heavier than the Democratic votes. Presto, the polls now turn out to say exactly what SkewedPolls assumed they should say in the first place. It is utter garbage. No pollling firm accepts this manipulation as valid.

    Note also that SkewedPolls found all the polls to be biased before the Denver election, but when Romney gained ground, suddenly SkewedPolls accepted their results. It’s “scientific” complaints are entirely determined by who is leading in the polls.

  23. Mike says

    Hey Mike, this is the problem, most democrats can’t spell. “lier” LOL try “liar”. Maybe if more dems had an education, we (the USA) wouldn’t be in the fix we’re in!

  24. danR says


    Those sneaky Democrats–going door to door and getting all those people out to vote. Campaigning face-to-face instead of throwing honest money at them.

  25. Enuf says

    I’m a moderate independent conservative and I see this sort of talk as just so much absurd bulluckey. Even Karl Rove’s polling site shows Obama ahead. To claim that there is a vast conspiracy to make polling favor Obama is insipid. More of the “I Am A Victim Look At Me!” mentality that has destroyed my former party, that being the Republican Party.

  26. mike says

    Romany is great lier and flip-flopper, he just keeps claiming and fooling people that knows how to fix economy but his fake Tax plan does NOT even add up for sure is not going to be passed,
    I am not going to vote for this fake Guy that his own record shows that un-employment, deficit and jobs outsourcing got increased and his state got highest unemployment rate in nation when he was governor of Massachusetts.

  27. Jm says

    Of course, we all know what is happening. Romney will win big. The left always tends to trust fake polls. Remember in 2004 they trusted the exit polls instead of the real ones! Go Romney!
