Given that the democrats have gone almost 100% liberal I don't know if that distinction can be made today--I guess in a few places. I just believe the word "conservative" is tossed around too carelessly in describing many politicians that are not conservative if one bothers to analyze their position on issues. Much as the "moderate" label has frequently come to describe politicians that are well entrenched in the liberal camp.
Given that the democrats have gone almost 100% liberal I don't know if that distinction can be made todayThis is true. A "conservative" Democrat is a relative term. At best such a beast would be in reality a centrist, and other than Zell Miller I am not sure I can think of any (and he is not as conservative as he has been playing lately, unless he has changed his stripes from his days as my Governor when I lived down there).
Today's Democrats are liberals, socialists, and communists. And those to the left of them make up the Nader/Green Party goons.
