South Carolina Sen. Lindsey Graham says Tuesday's first Democratic debate disgusted him.
"It made me sick," Graham, who is running for the Republican presidential nomination, said when asked by Tony Perkins of the Family Research Council's Washington Watch radio show.
"It makes me feel so sad that the Democratic Party has dropped so far when it comes to defending the nation," Graham continued.
Singling out the Democratic presidential contenders as weak isolationists, Graham said America's enemies would be hoping the Democrats took the White House.
"If I were ISIL, the ayatollah, Assad I would be pulling for the Democrats because their foreign policy is leading further from behind than Obama," Graham said. "Bernie Sanders would shut down the NSA program so we couldn't detect the next terrorist attack. Everybody had an isolationist, disengagement policy regarding radical islam."
Graham said that radical Islamic terrorists with a weapon of mass destruction would be a "nightmare" for the world and said keeping organizations like ISIS away from terrorists was one of the most important tasks of his lifetime.
