Mitt does poorly because he is a conservative.
Giuliani does poorly because he is so liberal the conservatives don’t fear Hillary more than him.
McCain benefits because the conservatives don’t pick Hillary over him when asked in polls, nor do they say they will stay home.
I'm sure you'd like to think that. But despite favoring gay rights, believing in madmade global warming, favoring gun control, and other liberal stands, for whatever reasons you want to imagine the fact remains that Mitt is strongly disliked by independents, which you admit. Add to that his problem with conservatives rightly mistrusting him and people like me who will never vote for someone so slimy, and he is utterly unelectable.
Why are you trying to push this unelectable fraud?
