Cruz doesn’t have a hold on all evangelicals...
“Rodriguez said he doesn’t support amnesty and wants Cruz to “continue to push for border security and stopping illegal immigration,” but added he wants
“the Sen. Ted Cruz of a few years ago that supported a pathway to legalization.”
Everyone but Cruz supporters know that Cruz wanted the aliens all legalized!
