Ron Paul's a pretty interesting guy, and I like him far more than his GOP opponent Michele Bachmann (who's toast as far as I'm concerned, following these events: http://motherjones.com/politics/2011/07/michele-ba... ), but the Tea Party in general scares the absolute hell out of me.
He's actually a rather sensible guy, but the newest members have really perversed what his party initially stood for; this idea that we need leaders who can relate to everyday people has turned into actual everyday 'common folk' who are unqualified - and, in some cases, flat-out unintelligent (see: Michele Bachmann or Christine O'Donnell) - representing the party, and horrifyingly sometimes getting elected. What results is the kind of thing you have in Minnesota right now with Bachmann, who put all her focus on battling the 'homosexual agenda' in schools, and consequently created a huge spike in the teen suicide rate in her district.
Honestly, I like Ron Paul, and I think he provides a refreshing, very logical perspective in many cases (there are times I agree with him - I used to work in the service industry, for example, so I love his argument that tips shouldn't be taxed!), but his party scares the absolute bejeezus out of me.
