Oh the FR establishment GOP locust are about to descend upon you and question your loyalty, call you a Democrat among other things. It’s standard establishment liberal GOP 101 playbook. They can vote for the Democrat, withhold money, trash in public or private and stab you in the back if you are a conservative but don’t you dare threaten to withhold your vote from one of their worthless leftist turds on principle you purist. Screw’em! After their behavior with Trump any leftist Bush re-tread that gets beat, the loss is totally on the establishment GOP at this point.
