Senator Lindsey Graham is having fun, but he's also experiencing a lot of frustration as he tries to overcome the far-right lunacy that has gripped the Republican Party.

Asked about climate change, Graham gave a lukewarm, self-deprecating response before having an outburst of frustration.

"I just want to win an election," Graham cried. "I'm tired of losing."

He then went on to point at Democratic race leaders Hillary Clinton and Bernie Sanders, criticizing Clinton's comment that she and President Clinton were "flat broke" when he left office, before turning to Sanders.

Graham shouted over moderators' attempts to regain control. "The Number two guy went to the Soviet Union on his honeymoon and I don't think he ever came back!"

The audience roared, too. Even the moderators had trouble not laughing as they cut away to a break.
