Hey, did you hear who’s maybe running for president? Everyone (except for Haley Barbour). At least that’s seemingly what each and every Republican politician wants us to think these days. And why not? Just say you’re “thinking about it” or “keeping your options open,” and the media will suddenly lavish attention on you as if you really matter. But not everybody does. Each Friday until the primaries truly begin, we’ll look at which of these prospective candidates are more likely or less likely to actually enter the race, along with a prediction of the likelihood that they’ll throw their hat into the ring. Excluded from this rigorous scientific analysis: any candidate we’re pretty sure is definitely going to run — guys like Mitt Romney, Tim Pawlenty, and Gary Johnson.
