I see a terrific amount of ink spilled talking about how Newt is 'smart', or Romney is intelligent and highly competent in a managerial way. These things are nice to have in a leader, but they are not the elephant in the room.
Before I can care about how much a prospective leader knows, I need to know WHO he actually cares about. Are me and mine part of his who, are are we rather the WHOM?
In that regard I view neither Romney nor Newt as acceptable, although Romney is probably a little closer to tolerable than Newt. If Palin was actually solid on demographic hegemony (which unfortunately, she is not), I'd happily support her despite the fact that she's likely on the very low end of the Second Sigma or near the high end of the middle of the First Sigma. Intelligence is only a discriminating factor between candidates if they can pass the Who...Whom test. If the candidate is your enemy at the existential bottom line, honestly, a reasonable man would prefer that they be stupid and of dubious competence.
