Newt, for one. In fact, Romney doesn't stand a chance of beating Obama, because he doesn't engender enthusiastic support among center-right voters. Remember that he LOST the last primary to one of the weakest candidates the Republicans have fielded in a decade or more?
If you'd had your radar tuned in properly over the last six months, you would have noticed that Mitt hasn't endured any sort of attacks or anal exams from the leftstream press. That alone, ought to inform you that he's Obama's hand picked opponent. The left knows that he'll be rightfully viewed as not all that different from Obama, and therefore, no kind of alternative at all.
Mitt will be perceived by the public as competent, and there have a great chance to beat Obama.
By who? 20% of Republican voters? Certainly not by the majority - especially after the news media gets through turning him inside out, and exposing his rotten liberal record.
By the way, your post comes awfully close to shilling for Mitt, which is verboten on FR.
Not shilling for Mitt. Just stating my opinion that he will win the nomination. And I think he has a good chance of beating Obama. Not saying he will, but he has a better chance than McCain. It all comes down to 6-7 states.
