I'll go on to add the following...
If you want to lump the Sharpton's, etc. as the same type of people as white supremacists...which I don't really agree with, it doesn't really change the math. If there were only one legitimate white candidate and all the white supremacists lined up behind him, it wouldn't seem weird...actually, it wouldn't be surprising at all. But - that wasn't the case...it seemed that many white supremacists were lining up behind Paul - and not other white candidates. Something about him attracted them...it was weird.
The same thing goes for conspiracy theorists. I seriously, seriously doubt that all individuals who buy into the idea of a vast right-wing conspiracy lined up behind Obama during the primaries...in fact, many probably lined up behind the woman famous for the term. However, the conspiracy folks that frequent the interweb seemed to really like Paul....during the primaries...when they had many to choose from, they seemed to choose him.
Maybe it is an unfair assessment...I don't have a strong thesis to support....I'm just calling it like I saw it...and it seemed wacky. I don't really get these vibes from Paul himself (though he did say some weird stuff)...but the high concentration of weirdos in the base of his supporters scared me off....
