As the five remaining Republican presidential contenders battled it out in the Houston debate Thursday night, former candidate Lindsey Graham entertained a crowd at the Washington Press Club’s annual congressional dinner with his true feelings on the 2016 race. “My party has gone batshit crazy,” Graham told the crowd. The South Carolina senator lashed out at GOP frontrunner Donald Trump, adding that he thinks the billionaire will lose in the general election “because he’s just generally a loser as a person and a candidate,” he said. Making light of his own failed campaign and subsequent endorsement of Jeb Bush, who dropped out on Saturday, Graham called himself the Dr. Jack Kevorkian of the Republican primary—before putting on a Trump hat.
