Turns out Perry was an elected Democrat. Romney was a Democrat donor. Huntsman accepted a Democrat nomination. Johnson is a Libertarian. Paul is a Libertarian. Bachmann was into Democrat politics in college ~ and probably after (but she's not real clear on that).
Santorum, Gingrich and Caine are lifelong Conservative Republicans.
BTW, my basic standard on "who's RINO' is if you are actually not even a Republican, then you are not a Republican. If you served as a Democrat or for a Democrat or donated to Democrats, you are a RINO.
If you are also a LEfTWINGTARD that's an additional problem.
I know what YOUR definition of RINO is (you've waived your ignorance over the topic more than enough for everyone to know) and it is not what the ENTIRE rest of the world means by the term. Former party affiliation has absolutely nothing to do with the word RINO. RINO pertains solely to the political policies the individual supports. Is he in line with traditional Republican policy stances, or is he aligned with positions which are traditionally Democrat Party positions. . . . nothing more, nothing less.
Until you know the lexicon and the meanings of terms in use, you cannot cogently enter the conversation.
