Is John McCain the only republican who can steal election from hillary clinton?

He was not liked by some republicans because he was seen as a maverick and/or liberal. I believe John McCain will win GOP primary because most likely likely hell win 75 - 80% of states out north and west such as california, new york, new jersey, arizona, and pennsylvania because is more of a moderate and got endorsements on behalf of Guliani and Arnold respected politicians. I see huckabee just splitting the south with romney and mccain taking 1 or 2 of traditionally southern conservative states. I think he is more likely to be hillary clinton because he gets alot of support from conservative democrats and independents. He is also can win moderate states that are blue states such as california, arizona, and michigan and will most likely win every red state like bush did in 2000 and 2004 because ms clinton is too far to the left and her gender will not help her among south which is very conservative.
