Both Trump and Rubio seem to be operating under the presumption that they can win without the support of the conservatives who back Cruz. Although it’s possible perhaps, even probable, that Trump can get the GOP nomination with his current base of support, it’s NOT true for Rubio. He’s making a major blunder by attacking Cruz and ignoring/avoiding conservatives at things like CPAC. Even Romney understood that he needed to at least pretend that he wanted the support of conservatives.
“Severely conservative.”
