You are kidding, right? Rush a "convenient conservative"? I've been listening to Rush since May of '89 and never once have I heard him take the easy way, i.e. the liberal way, out of anything. Case in point, his refusal to really get behind McCain in '08. He knew Mr. McCain was a moderate at best and refused, I believe as Rush put it, to "carry his water".
LOL, Rush supported ROMNEY!!! in 2008, over his two challengers.
