Ten days from now, I’ll be trying to figure out what happened. My biggest fear is that people will stay home, discouraged by the steady drumbeat of doom from the Main Stream Media, based on polls that are probably inaccurate. I say this based on several years in the public opinion business. This election is unlike any in history, and the only way to approach it is to vote. Then, if there is reason to be discouraged, do so after the election. Consider this:
…This is the most unpredictable election in my memory, and, indeed, I can’t even think of one that rivals it….
…Consider the tools we usually use to project electoral outcomes. They are, without a doubt, providing as many questions as answers in this most unique electoral cycles.
Usually, an election forecaster makes the bulk of his/her determinations about how an election is going to go based on the polls. But this year, that has proven more difficult to utilize, and for two reasons.
- The Likely Voter Thing: We have been told for years that pollsters use "likely voters" because it provides a more accurate landscape for taking a snapshot of the electorate. After all, what is the use of recording the preferences of voters who aren’t, in all probability, going to vote on Election Day, anyway?
While this is inherently logical, there is a problem with that assessment this cycle. There have always been gaps between the outcomes of polls between "likely voters" and the less restrictive screen of "registered voters." Historically, that gap has equated to better Republican performance among likely voters (as Alan Abramowitz noted over at Pollster a while back). But that hasn’t always been the case. In the Democratic wave election of 2006, the majority of the polls which offered both LV and RV data had their LV screens slightly favoring the Democrat. What’s more (and this could have big implications for 2010): those screens almost universally (75% of the time) overstated the Democratic performance in the race.
Indeed, in the last two election cycles, the "registered voter" screen has been closer to the final outcome more often than the "likely voter" screen. And it wasn’t all that close: the RV screen came closer 57% of the time, the LV screen was closer to the truth 38% of the time, and they split the difference 5% of the time.
Another unique feature of the electoral cycle has been the width of the gaps between RV’s and LV’s. In the 2006 and 2008 cycles, the majority of the gaps between RVs and LVs consisted of gaps ranging from 0 to 2 points. In this election, gaps as wide as 13 points have been reported (an early October CNN poll of Nevada). Of course that has been owed to the most oft-used phrase of the cycle: the enthusiasm gap. More on that later.
- The Pollster Hegemony Thing: Around two months ago, I noted that a majority of the polls in my database for this cycle either emanated from Republican private polling or from Rasmussen (which, of course, could easily be described as Republican public polling). As the trickle became a flood of data (what was, at that time, around 1000 polls is now 2040 and counting), those numbers have changed, but only slightly. Even at this point, 47% of the polls released in this cycle have come from GOP or GOP-sympathetic (read: Rasmussen) sources. By contrast, just 8.5% of the polls have come from Democratic sources.
This can be read two ways. For one thing, in 2006, it was Democratic polls that swamped polls from GOP sources. Read this way, this can be interpreted as a bad sign for Democrats. Republicans are releasing more polls because…well…they can. The data contained in them is data they want to have the public consume. But there is an alternate viewpoint: they can also simply be skewing the reality of the electoral situation. As Nate noted last week, these polls come with a thumb on the scale. If (as has happened this year), twice as many sponsored polls have been come from the GOP side as the Dem side, it will paint a picture that is, perhaps, overly optimistic for the Republicans… [emphasis added]

I encourage you to read the entire article.
Based on my experience, the polls I have seen, and my knowledge of candidates’ positions, here are my projections. I project that the next Senate will have 51 Democrats, 47 Republicans and two Independents, leaving an effective net of 52-48 (counting LIEberman as a Republican). I project that the House will have a slim majority, but there are too many dead heat races to say whose majority it will be. Finally, I project that there is a strong possibility that I have no idea what I’m talking about! There are just too many variables.
So, in conclusion, I urge you to act as if there were no polls. In national races I urge you to vote for Democrats, with the caveat that in rare cases, that is not ethically possible. I could not in good conscience vote for Blanche Lincoln, if I lived in AR, for example.
Vote!
