I have heard a lot, a real lot, of anecdotal stuff, and a lot of it I dismissed because the people were just strong Newt supporters and easily upset, but that was a while ago, and I've since changed my mind. the Florida GOP moved heaven and earth to get at Newt, and I believe crossed the line a few times. Then Tennessee... and I am sure they have done similar stuff to Santorum, though don't know those details. Mainly, if half the stuff I have heard is halfway accurate, the RNC is almost criminal, and totally unethical.
After 2008 and the treatment of the TEA Party by the GOP, I think all state GOPs are establishment. It’s the local folks who are the conservatives. Sort of the same way that all our institutions are corrupted by liberals because they put all their energy into amassing power, rather than working at a job and raising a good family, the top jobs in our republican party are held by the RINOs while the rest of us work and raise children with good morals.
