No surprise about Giuliani, but Edwards dropping out today did shock me. I figured him to wait until Super Tuesday, in which he would have been likely to secure a bunch more delegates, and then drop out to wait for the convention and a role in whatever brokering goes on there if Clinton or Obama can't lock it up.

Of course, since Edwards has been playing himself up as the one "grown-up" in the Democratic debates, then dropping out can be viewed as the "grown-up" thing for him to do, given the reality of the status of his campaign. Plus, it better positions him to once again be considered a potential running-mate (though I doubt that that would happen - certainly not with Clinton and I don't think he adds much of anything to an Obama ticket)
