SEN. RAND PAUL (R-Kentucky): Well, you know, [Hillary Clinton] is seen as a leader in her party and the potential leader in their nominating process. I think it's a mistake to let someone -- I'm not talking about whether I'm running, but to let someone run unopposed. In the past we haven't gone after the opposing party's nominee, to say who they are and what they represent. I think she is going to try to say oh, I'm different than President Obama. He's very unpopular. But I have different policies. She was part of his administration and I really don't know of many, if any, policies they disagree on.
