For horserace watchers, Chris Cilizza has a good look at the Democrats' lead in the generic congressional ballot. The nickel version is that Dems are doing about as well as they did in 2006. So that's promising. Cilizza goes on to run down the 20 most competitive races, a project, he says, that's gotten easier. "In short, the playing field is going to get far larger over the next few months. Unlike in past election where we had to struggle to get the House Line anywhere beyond 10 seats, it's a HUGE undertaking to limit it to 20 seats now."
