No, Matt Drudge, the McCain Gap Isn't Closing

Calm down, writes Nate Silver at FiveThirtyEight.com. There's no need to panic over a couple of polls, trumpeted by Drudge, showing the race tightening. “Man, I thought I trained you guys better than this,” he notes. One, the Mason-Dixon poll, shows Obama up by only 4 in Pennsylvania. The other, a Fox News poll, has him leading by just 3 nationwide. Neither is persuasive evidence of real movement, Silver says.

Sometimes, writes Silver, a poll just comes up with an aberrant result. It doesn’t mean the pollster is biased, or even wrong. It’s just part of the nature of random sampling, especially for pollsters who don’t weight their sample by party. Nothing Silver’s seen adds up to evidence of a tightening race. He reiterates: for a game-changer, John McCain would need to be polling "within 2 points in 2 or more non-partisan polls in at least 2 out of the 3 following states: Colorado, Virginia, Pennsylvania."
