Matt Drudge has actually said in the past that he is more liberal than most people think.
Andrew Breitbart used to help him with the Drudge Report, and when he left to start Breitbart news, Drudge made a deal to hotlink the majority of his news from his site. Thats why so many links on Drudge are from Breitbart. Which, IMO is pretty conservative.
Best blog IMO?
