Watch Lindsey Graham go From Hating to Stumping for Ted Cruz
(CNN) -- It's that strange time again in American politics when politicians support candidates they have repeatedly said they can't stand. For months, South Carolina Republican Sen. Lindsey Graham has been warning the nation about Texas Sen. Ted Cruz. But on Thursday, Graham told CNN that not only is he supporting Cruz, he's fundraising for him. Graham pointed to Donald Trump's rise as the reason, explaining that Cruz might be the only one to stop him.
