Bill Bradley today became the latest high-profile Democrat to endorse Howard Dean. The prospect of Bradley and Gore, who fought a bitter primary struggle four years ago, coming together to endorse a candidate in this one is a peculiar and interesting one. I think, as I suggested before, that it shows less about Bradley than it does about Gore - who was castigated in 2000 for failing to run the kind of aggressive populist campaign Bradley and now Dean is associated with.
