The New York Times' Dean Murphy seems to think so, and in "In Exulting Bush Throngs, Just a Little Bit of Anxiety" he shows that Republicans aren't nearly as confident about this election as you might think. He leads with this:

There is a good deal of nail biting going on at the mostly picture-perfect campaign rallies held for President Bush.

Terry Buck, a first-grade teacher from Cleveland, feels the nervousness. So does Jim Nichols, a municipal purchasing officer from Saginaw, Mich. Both turned up this week at big events for the president near their homes. While they cheered endlessly, they also fretted some.

Ms. Buck and Mr. Nichols say the election is much too close. Mr. Bush should be trouncing Senator John Kerry. Something is not quite right, and like many of their fellow Republicans, they share the belief that the news media has played a role by skewing coverage in Mr. Kerry's favor.

For unsettled Republican voters in battleground states like Ohio, Pennsylvania, Michigan and New Hampshire, the last leg of the presidential contest has at times been more of a group therapy session than a victory march.

There is certainly no panic, Mr. Nichols says. Mr. Bush's supporters believe in him too much for that. Some of the loudest ovations come when the president predicts, as he almost always does in his speeches, "a great victory on Nov. 2."

But for every measure of hope there is some measure of anxiety gnawing at the adoring crowds that are shadowing the president the last days of his re-election campaign.

"I haven't talked to anybody who is not concerned," said Mr. Nichols, who took a day's vacation on Thursday to see the president at a hockey rink in Saginaw. "I think it is closer than it should be."
