Well, from the polling, I'd say they would be a lot more secure than if they again sided with the Democrats and Obama. The Establishment Republicans are reeling now from the backlash. Probably the most experienced of any Establishment Republican to enter the race was Senator Graham. He was lucky to poll 2%. You are terribly mistaken when you claim it all has to do with rabid rightwingers. Many old-school Democrats, women, some few Blacks, and a whole load of Independents are pissed off with Obamacare and the failed economic and foreign policies of Obama and the Democrats. It's not all Right Wing.
