Who was this candidate not chosen by the GOP? Newt? Smart guy, probably would have been more aggressive in the debates, but his personal baggage would have been exploited constantly. Santorum? Would have been presented as a rigid ideologue who lost his Senate seat in a landslide ( I voted for him all 3 times in PA). Rick Perry? A short flash of popularity but self-destructed; and didn't toe the tea party line on immigration. Ron Paul? his positions on defense and currency pulled in some libs, but alienated a lot more of the base. Huntsman? RINO who accepted an ambassadorship from Obama. Romney actually had to overcome a lot of opposition from GOP "establishment" figures to win the nomination.
