I don't know that many people who hate Paul himself. He's a pretty harmless isolationist crackpot who doesn't command enough respect to ever have any political clout.
What a lot of people do hate is his small army of smug, smarmy little Paultard disciples, who have tried their overbearing, repulsive best to split the Republican Party. Some of them are smart enough to know their only realistic goal is to defeat Republicans and make it easier for socialists to take office.
Luckily, they represent a tiny sliver of the political spectrum that makes Dennis Kucinich look mainstream by comparison. They pretty much took over CU, which isn't much of a prize. They show up here from time to time, but usually don't find it a very hospitable locale.
