Nate Silver noted yesterday that the number of competitive House seats this year is fully double the usual number (and remember, the last two cycles were wave elections in their own right.) Which means there’s going to be a lot of stories like this over the next three weeks. And I promise you, every last one of them will be fun, fun, fun.

As Republicans made new investments in at least 10 races across the country, including two Democratic seats here in eastern Ohio, Democratic leaders took steps to pull out of some races entirely or dramatically cut their financial commitment in several districts that the party won in the last two election cycles.

Representatives Steve Driehaus of Ohio, Suzanne Kosmas of Florida and Kathy Dahlkemper of Pennsylvania were among the Democrats who learned that they would no longer receive the same infusion of television advertising that party leaders had promised. Party strategists conceded that these races and several others were slipping out of reach…

The National Republican Congressional Committee, the party’s election arm in the House, can afford to make the new investments because the U.S. Chamber of Commerce and a host of newly-formed political organizations have come to the aid of Republican candidates who have far less money than the Democratic incumbents.

That’s the Times’s way of telling you why Democrats can’t stop screeching about the Chamber et al. It’s not because they’re funneling shady money from foreign donors into campaigns; it’s because, as has been noted repeatedly this year, the Democrats are getting destroyed by conservative outside groups. Their only defense at this point is to smear them and hope that voters pay enough attention that they’ll instinctively recoil from any ad that carries the Chamber’s name at the end. It ain’t much, but it’s all they’ve got. As for the Dems named in the excerpt, anyone remember Suzanne Kosmas? She was a holdout on ObamaCare but ended up voting yes after she and The One had a chat about protecting NASA jobs in her district. That was her price, and she took it. And now they’re pulling the plug on her until the final week of the campaign.

Speaking of desperation, according to James Carville’s polling firm, Democrats are now so weak that blaming Bush actually costs them a few points among voters. Why? Simple: Economically, invoking Bush actually makes people nostalgic for the not-so-distant past. So they’ve officially got nothing to excite voters now, aside of course from Chamber-bashing. Oh, and this. Click the image to watch.
