Jim Geraghty sounds like he was inspired by Bob Costa’s observations at the Capitol last night:

Unless we capture Osama bin Laden or aliens land, it’s going to be a good year for Republicans. The question before us is how good. The cake is rapidly baking; in Ohio, they’re voting already. That’s not cockiness, that’s just seeing what’s going on.
Right now, I prefer the Rex Ryan approach [to “don’t get cocky”] to the coming midterms: Act like you and your guys can beat anybody else out there any day of the week if everybody does their job. Set expectations high, then work to meet them. I don’t want to hear that Republican strategists at the national committees feel good about winning the 40 seats they need to control the House. I want to hear that they’re worrying that they won’t meet their expected goal of 70 to 80. This is the political environment that every Republican candidate has been waiting for since at least 1994, if not a generation.
