Well first she’d have to win the nomination, before that she’d have to announce. Until either of those two things happen, she ain’t winning a damned thing, capisce?
Actually, she is. As we speak, she's winning the battle of attrition. As Romney and Perry and Bachmann, etc., lose momentum and drop off the vine, more and more political oxygen becomes available for someone like Palin or Christie, or whoever else had the strategic genius to stay out of the early, meaningless skirmishes.
Cain will fade again as soon as someone new pops up; he's already proven his inability to hold the interest of the voters when faced with actual competition.
Palin is right on schedule... and flying under the radar, and way over your head.
