If you had actually LISTENED to her.... you would know the answer.
Just because is causes cognitive dissonance with the left and RINOs doesn't mean it's not a valid answer.
* Bring conservative principles back to the RNC (small government, get government out of our lives, lower taxes, 2nd amendment support, state's rights, small business support, lower taxes, strong defense, no-nonsense foreign policies). Conservatism works every time it is tried.
* She could be a credible spokesperson for energy, drilling, etc in light of sane environmental initiatives.
* She could, on a daily basis, take the wind out of Barry's Marxist sails on a host of his anti-American issues (bank take-overs, nationalization of large sectors of the economy, socialism, class warfare, generational theft, bigger government, job killing). Her media appeal would take away from the daily barrage of "new plans" put out ad nauseum by Barry, Rahm, Steffy, and 'Astro-Turf' Axelrod. She would be a countervailing force to the crap we get from the White Crib on a nearly hourly basis. If Republicans embraced the Twitter, Facebook, MySpace internet viral communications, it would be a direct hit against Barry's minions.
* She could - and this is the biggest reason she should take over the RNC - help with a 1994-esque take-over of both houses and start blocking the hopey-dopey-changey-strangey crap we have seen for the last 6 months.
The Presidency would be OK for her later on, but short-term we need to do things that set the stage for long-term solutions, that is, GET THE SENATE BACK (which will run to the SCOTUS issues), get the HOUSE BACK (which runs to spending and social engineering issues).
We need to be strategic, not knee-jerk, and Sarah may be an important rallying point to meet these objectives AS THE HEAD of the RNC.
But I could be wrong....
