As you’ve already been told a thousand times, with only a day to go before the Iowa caucuses, the polls are showing a statistical three-way tie between Barack Obama, Hillary Clinton and John Edwards atop the Democratic field, and a similarly close two-way race between Republicans Mike Huckabee and Mitt Romney.
But the polls are probably wrong. Or maybe they’re right -- we won’t really know until Thursday night when the actual results are announced. And that’s the problem -- the media have given the polls so much emphasis that the actual results will only matter to the extent that they differ from the media’s pre-election expectations, i.e., only to the extent that this week’s polls are inaccurate.
In just the last month, RealClearPolitics has posted the results of 55 pre-Iowa caucus polls (27 for the Republicans, 28 for the Democrats). These are mostly media-generated polls, with a few conducted by universities. It’s because of these polls that reporters think they know who is and is not a frontrunner, who is and is not rising and/or falling, and who is and is not hopelessly behind.
