McCain is intensely disliked on Free Republic, but not by the Republican Party base in general. He could end up being the nominee almost by default unless someone else emerges who can make a convincing case against him.
Although not even the most profound and compelling rhetoric could persuade me from voting against the anti-RKBA RINO McCain, I am intrigued by your inference that there is ANYTHING redeeming in his character. Taking your assertion about the Republican Party base in general at face value, please would you explain just what he has done that makes him appeal as you suggest: I am having trouble recalling any positive actions on his part that were more than an occasional towing of the party line.
As for Giuliani, he is a fascist JBT, who would go over like a ton of bricks in the heartland.
