None of them are comparable to Reagan. Not one. But Perry wasn't making a comparison. So the title of your vanity is incorrect.
If I had to pick who was the closest to Reagan among the three of them, I certainly wouldn't pick Romney. So that leaves Huck or Rudy. The former is a social conservative, fiscal liberal and the latter is a social liberal, fiscal conservative. Since the Reagan Democrats liked Reagan's fiscal conservatism, I guess I'd say Rudy was closer to Reagan than Huckabee was.
You present this video as if Perry made a glowing comparison of Rudy to Reagan. He didn't. It's a disservice to FReepers to present incorrect information.
There is a lot of that going around, isn't there?
It is truly discouraging...
