Housekeeping

Just a couple minor changes. I've posted some links to some factchecking sites and Pollster.com. I find these sites useful, you might too. Also, I've opened up comments so that people can leave anonymous comments. I frankly didn't realize that my settings required people to sign up to Blogger to comment. So that's changed for now. If we start getting a lot of spam or Ron Paul supporters showing up in the comments, I may put some mild restrictions up.
