Speaking at the Washington Press Club Foundation Dinner, Senator Lindsey Graham mocked all of his former rivals in the 2016 Republican race on Thursday night, claiming that his party had gone “bat**** crazy,” saying that if you killed Ted Cruz on the Senate floor, that “nobody would convict you,” and he said that he would endorse Donald Trump in the hopes “the grim magic” of those he endorses dropping out of the race “still exists.”
