The Dean scream kinda reminds me of the Dukakis decision to do the photo shoot in that tank.
The 60s wasn't when the Southern Democrats left - it was a process that had been in motion for a few years, it just peaked at that time.
If you're talking true liberals, the last to win the nomination was George McGovern in 1972, and when he moved more towards the center for the election (eliciting the help of Mayor Daley in Chicago as well as other Dem. leaders) was when his support base dropped through the floor.
The country hasn't moved any more right; what the right is has changed. It is just recently that there is a lower percentage of Democrats in the country than Republicans

The fact is the Republicans have done a great job of redefining who they are, and the Dems just haven't caught up.
