He was the other Texan in the race. But now he's the only Texan still running for president.
"This is criminal. This is immoral. It's bad economics," Paul said.
Paul drew another large crowd at the College of Charleston Thursday morning. He's spent only six days there campaigning, and yet he was polling well ahead of Gov. Rick Perry, who called it quits just a few miles from Paul's overflow event.
"How do you think his dropping out affects your campaign?" we asked Paul.
"I think it will help, but I wouldn't claim that every Rick Perry voter is going to come my way. My guess is it'll probably split. You know his numbers were getting pretty low," he replied.
Paul says he thinks Perry's withdrawal will have little effect in South Carolina Saturday. He says the governor lacked a dynamic campaign there despite committing a lot of time and money to the state.
For his part, Paul has not focused on the Palmetto State. His campaign says they've spent little money there, won't spend much in Florida and that they are looking to key caucuses in the West and Midwest next month. And they expect to stay in the race long after a lot of others have joined Perry on the sideline.
"Do you think it'll come down to Romney and you?" we asked Paul.
"Certainly looks like it could be at the rate we're going here. And even with the election being very important, we still have quite a few more to go," he said.
We asked Paul about his tendency to be a little more aggressive in the recent debates and he said he's aggressive when it comes to defending his beliefs and the American system. He also says he expects Thursday night's debate to be a slugfest even if Perry isn't a part of it.
