The GOP (the right-wing party in the United States) is trying to appear young and hip by having a URL shortener (like bit.ly) for Twitter.
They aren't filtering the URLs. They also have the Republican chairman walk out onto the screen and make a pitch for the party. It's hilarious to watch him talk about the "new GOP" in front of hardcore porn. For an example, I'll link to Fiestafan:

Just imagine the possibilities, LOL.
