Yes, I suppose I'd have to vote for McCain over Lieberman, too, in part beacuse Lieberman supports McCain on issues like Global Warming.
I think with regard to their voting records you have to take into account that Senator McCain rarely takes a position to the right of Republicans, and Lieberman often takes positions to the right of Democrats even though he usually ends up voting with them.
Given the greater freedom the President has to set his own agenda, I think a President McCain would certainly be much further to the left than his voting record, and a President Lieberman MIGHT be more conservative than his voting record, although I don't think he would be.
Well, Lieberman will obviously never get a chance to be President anyway... But McCain has a legit shot at it. I'd vote for McCain over any of the Democratic candidates, but there's no doubt in my mind he (as Liberman would also be)a disaster as president.
I have to admit I bought into the Lieberman hype until I took a closer look at his record.
There are some good conservative Republicans out there. I hope one of them gets the nomination rather than McCain.
