Ann Coulter was saying something similar the other day, during a radio interview (on Hannity, I think).
OTOH, all this takes second place to somehow, someway, destroying the Democratic Alinskyite "personal destruction" machine. Starting with Media drones who are kneejerk liberal Dems or actual "Progressives" (neo-Stalinists).
Coulter wants Romney. Romney's hope is that one clear anti-Romney does not emerge until it's too late.
The Dems also didn't have a nutbar spoiler like Ron Paul in the field as well.
So comparisons to the 2008 Dem primary are of very limited use. Plus, this is from NR, who also wants Romney, so take it with that very large grain of salt as well.
