Claim to fame: Graham is a hawk's hawk, arguing consistently for greater intervention in the Middle East, once arguing for pre-emptive military strikes against Iran. His influence was credited for pushing President George W. Bush to institute the 2007 military 'surge' in Iraq.

Some of his critics have taken to call him 'Grahamnesty,' citing his participating in a 2013 'gang of eight' strategy to approve an Obama-favored immigration bill. He has also aroused the ire of conservative Republicans by supporting global warming legislation and voting for some of the president's judicial nominees.
