It's a lose lose situation anyway. First, why even consider romney? He's not conservative or in touch with the mainstream. And santorum...while the most idealistic conservative of the three, panders too much. He's too nice and ent be able to defend his values and past decisions...its the one thing I can admire about Ron paul, the look, is that no matter how wrong he Is, he can defend his values to the death.
Newt is corruptable and cruel which can have a two edged sword. You want him to be cruel to the cruel, but after 2 years in office, ill bet you he will become cruel to the kind, which would be Israel.
