Paul: 'I'm probably the most unpopular person in Washington'

strong>SPARTANBURG, S.C. — Kentucky Sen. Rand Paul is ramping up his anti-Washington message as he tries to compete for support in the third earliest voting state.

The Republican presidential candidate told an intimate group of supporters at a local burger joint Friday that he "may be the most unpopular person in Washington" following his recent attempt to block passage of the budget agreement between congressional leaders and the White House.

"I made them stay awake until 3 o'clock in the morning," Paul quipped as supporters raised their milkshakes and cheered. "At 2 o'clock in the morning they came over to my desk and said, 'You've spoken your peace, right?' And I said, 'Aren't I guaranteed one more hour?'"

"They looked at me horrified and angry and said some words I can't repeat with the kids here," he added.
