Rand Paul is not so bad, yes some of his views are extreme but it could be just to pacify the RWNJs in his party. Who knows at a minimum his presidency would be interesting and I think he would cut both ways not just against the opposing party.
Next is Jeb and his shady real estate in Florida. If you think Whitewater was interesting Jeb took it up a notch. After that... Marco who can't say for sure if he thinks the Universe was created in 7 days 10k years ago.
