"For Democrats, even a gain may feel like a failure"

That's the headline for an article at the New York Times.

In most midterm elections, an out-of-power party picking up, say, 14 seats in the House and five seats in the Senate could call it a pretty good night.

But for Democrats in 2006, that showing would mean coming up one seat shy of taking control of both the Senate and the House. And it would probably be branded a loss — in the case of the House, a big one.

For a combination of reasons — increasingly bullish prognostications by independent handicappers, galloping optimism by Democratic leaders and bloggers, and polls that promise a Democratic blowout — expectations for the party have soared into the stratosphere. Democrats are widely expected to take the House, and by a significant margin, and perhaps the Senate as well, while capturing a majority of governorships and legislatures.

I'd say that's an understatement. Many of the left-wing and Democratic (not necessarily the same thing) blogs I've seen have been practically salivating at the polling numbers for this election. Enough with the polls - let's see the results.

You remember 2004? When Kerry was supposed to whip Bush over the head with an Iraq-War club, and the Democrats were supposed to take control of something?

These expectations may well be overheated. Polls over the weekend suggested that the contest was tightening, and some prognosticators on Monday were scaling back their predictions, if ever so slightly. (Charlie Cook, the analyst who is one of Washington’s chief setters of expectations, said in an e-mail message on Monday that he was dropping the words “possibly more” from his House prediction of “20-35, possibly more.”)

Some Democrats worry that those forecasts, accurate or not, may be setting the stage for a demoralizing election night, and one with lasting ramifications, sapping the party’s spirit and energy heading into the 2008 presidential election cycle.
