So now the Zogby poll, which had seen more Kerry strength than most, is picking up a Bush surgewhile the Rasmussen poll, which trended for Bush, is seeing a Kerry bump.
Im glad that I am out of the business of polling U.S. elections.
The difficulties of accurately surveying presidential prospects have become ever more daunting with each new election cycle. The growing difficulties account for the wide fluctuations in survey data.
The main variant in the data relates to the likelihood of a person actually voting. With half of the potential electorate normally forsaking the franchise, pollsters have great difficulty in identifying who will actually participate and weeding out the real voters from those who will stay home.
Most turnout models developed in recent years are predicated on the relatively low turnouts in recent U.S. elections. In 2000, for example, only about half of those who were eligible actually cast ballots. Even in a high turnout year like 1992, just 53 percent of the voting-age population actually cast ballots.
But every indication is that this years turnout will dwarf our recent experiences. With record numbers of new voters coming on the rolls and get-out-the-vote operations generously funded by independent political committees released from any effective controls by the so-called campaign-finance reform, participation is likely to soar. The massive funding of these supposedly non-partisan political committees has empowered massive drives to sign up new voters and to generate a high turnout.
The closeness of the 2000 election is generating new voters. With party feelings approaching fever pitch as the election nears and emotional issues like terrorism, gay marriage, recession and the like dominate the campaign, turnout seems likely to be very, very high.
The truth is, no modern pollster really has any idea what to expect if turnout reaches the high 50s or closes in on 60 percent.
Theres no good way to estimate turnoutmost people wont admit to not planning to vote.
And while there are models for the composition of the electorate at a 50 percent turnout, there is no data on a modern American election with a substantially higher turnout. Everybodys guessing.
Who will the new voters be? The conventional wisdom says: downscale Democrats. When one compares the vote in presidential election years with off-years, the difference between the two usually consists of low-income, poorly educated and minority voters who tend to back Democrats. The increased interest of younger voters in this contestlikely due to the waris also probably a Democratic advantage.
But all groups of voters participate far below the 100 percent ideal and there is a lot of room for growth among all voter groups. GOP voters, while better educated and more likely to vote, have well below unanimous participation. And it may be easier to get Republicans who usually dont vote to cast ballots than to dredge out less well-educated and more alienated Democrats who have stayed home in the past.
Techniques for getting out the vote have also changed as many states, Texas for example, encourage early absentee voting. Workers of both parties throughout Bushs home state are regularly visiting nursing homes or college campuses collecting absentee votes during the three-week window before Election Day during which balloting is permissible. Mail-in voting, pioneered in Oregon, is also dominating the counts in many states. In assessing trends, pollsters must find out who has actually already voted, making changes in their opinions irrelevant.
Cellphones are part of the problem. Political survey research is based on a proper geographic distribution of the sample, reflecting residential and voting patterns. But cellsunlike landlinesare hard to pin down to precise locales. Also, pollsters cant tell if they overlap with landline respondents.
Finally, people are fed up with direct phone marketing. The era when voters welcome participation in a survey is as distant as the age when people looked forward to getting mail. So completion rates in phone polls have dropped, raising concerns about the techniques accuracy.
The Internet, which gets around the concerns of phone polling, still under represents the poor and the elderly. And even online polling can only reach those willing to take the time to participate, so the sample is still suspect.
As Election Day approaches, two trends will dominateneither good for Bush. Downscale voters will begin to pay attention and be included in surveys of likely voters. Since they largely vote Democratic, this is good for Kerry. Also damaging to Bushs prospects is the fact that undecided voters tend to break in favor of the challenger at the very end.
But, again, all that holds in a normal year. We wont know if its still true until next Tuesday night (if then). Its a tough year to poll.
