RINO (Republican In Name Only).
But Romney is not a RINO- and hasn't been since BEFORE he was Governor. He learned how to govern while he was in that position. There is a night and day difference in his decisions before and after his tenure there. Check his record and you will find that the Tea Party and liberal media have incorrectly labeled him- he as conservative as they come!
and IF you want to point to the HC law in Mass- THAT was a Reagan idea from the start- Romney just made it happen!
