I like Bayh for a Democrat, which really isn't saying much. However, he is not a conservative. Take a look at some of his ratings, his voting record is more liberal than his rhetoric.
Zell Miller is a conservative Democrat. Bayh is a centrist at best, and even that is a stretch.
Zell Miller is NOT a conservative Democrat, Jo Lieberman, Evan Bayh and John Breaux are conservative democrats... Miller is these days (back in the 1990's he was more leftwing) pretty much inline with the mainstream of the GOP... once again he is even less of a democrat than Lincoln Chafee is a republican IMHO...
