Even though their bases were quite different (though perhaps less so than many believe), Romney.
- Both as rich as f**k.
- Both have a history of social liberalism.
- Both have taken tough stances on immigration and China.
- Both possibly wear wigs.
- Both Northeastern.
- Both were up against a weak field.
- Both established themselves as frontrunners early, with the race becoming defined as "them vs. the rest".
- Both were briefly threatened by a token African-American Republican.
- Both narrowly lost Iowa in a three-way split but won big in New Hampshire.
- Both of their final serious challengers were religious nutcases.
The biggest similarity is that they both argued their business experience made them qualified to be president...an argument that appeals to many Republican primary voters. Romney only
had the one term as a governor, which he never mentioned on the campaign trail unless someone attacked it. I bet there's more Romney '12/Trump '16 PRIMARY voters than people think.
Ultimately though, I think the choice is Cain.
