JMHO’s: Palin will never run for office again. Santorum is squishier than you think, and widely perceived as a sourpuss. Romney will try again. Jeb will run. Romney and Bush will kneecap Santorum and the media will roast him on a spit. Voting doesn’t work anymore; we’re just going through the motions, like a bad marriage appearing at holiday dinner.
Oh, and Hillary won’t run.
JMEHO, but I don’t think there’s a chance Romney runs for anything again. Don’t know about Palin, and why do you say Hillary won’t run?
