IMHO, every pubbie is a RINO until they prove themselves to be conservative when they have a chance to govern. Trust no one...to be what THEY say they are.
I've gone through this before ~ 7 out of 10 Republican candidates who signed up with the RNC had been a supporter/worker/donor for some party other than the Republicans some time in their life ~ and that included Ron Paul and Mitt Romney.
Romney did something I never heard of before ~ as a Republican office holder he made serious donations to Democrats running for office.
BIZARRE!!!
The only NON RINO Republican candidates were Herman Cain, Newt Gingrich and Rick Santorum.
All the others were tainted ~ some horribly ~ some less so ~ but just with that little piece of the definition, they were not really authentic born and bred Republican hard cores.
If you want to pin down leftwingtard proclivities, that'd be Johnson, Huntsman, Romney, Paul ~
