In any case, Howard Dean said stuff like "we gotta win guys with Confederate flags on their pickup trucks", but the true leftists today castigate them as gap-toothed racist hicks. There's a lot of selective nostalgia going on for the Dean era. He elected blue dogs, not Bernie Sanderses.
Meh, I'm lefty, but I'm also a pragmatist. If we want to win and have some semblance of progressive policies pass, we need progressives in safe Dem seats, and Blue Dogs to win GOP seats.
Now the question I'm really concerned about is what lefty policies can the Blue Dogs present as populist and desirable to the moderate/light GOP voter?
