I believe you mean "Republican elected leaders".
Good point. Don't there exist Liberal Democrats and Conservative Democrats?
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.
Conservative Democrats?There are several hundred Democrats in Congress (House and Senate). Can you name any more conservative than, choosing a RINO at semi-random, oh, I don't know, Arlen "Magic Bullet, Scottish Law" Specter?
If you can, then you probably can count them on one hand.
