To underscore the point I made below about weekend polling favoring Kerry, here's an article from the Kerryspot:

I am reminded of this Larry Kudlow column from July 2000:

I called one of my old polling friends, Republican Ed Goeas, who worked with me years ago in Christine Todd Whitman's tax-cutting 1993 gubernatorial victory in New Jersey. Along with Democrat Celinda Lake, Goeas publishes the highly-regarded Battleground Survey. He told me to be careful about reading the polls. For one thing, it really matters if polls are conducted during the week or over the weekend. He told me that "political pollsters don't poll on the weekends. They prefer Sunday night through Thursday night. Weekend results are just not reflective of where a given race really is."

Goeas explained that more Democrats are found at home on the weekends, especially blue-collar Democrats. He added that "anyone who spends 20 to 30 minutes during the weekend talking to some pollster is not normal."

Still, with Election Day on a Tuesday, weekend polls are the only polls we're going to get right before the election.
