Playing devil’s advocate, obviously Romney’s main competition is Perry and Cain is nothing more than an boutique candidate. No Perry, Romney is easier.
Totally agree; Perry and Romney are still the frontrunners in my opinion. Cain is a longshot, although his recent strong performances should give him the fundraising ability to remain in the race a bit longer.
If one or both of the frontrunners implode he could find himself in a very good position. I don't think any of the remaining (announced) candidates are credible threats to win the nomination. No traction, not enough money, and in some cases personal credibility issues...
