Why? Because he's a bad ass. But also because, unlike some of the douche bags complaining about him but not doing anything, he knows how to give his best. That and he has kick ass friends to who support him.
One of them is Katy Perry, one of the world's most talented singers. Here's here awesome dress she wore to show support for the best president since Abraham Lincoln.
Bravo, Katy Perry. It takes courage to do such a thing, even though it's right. It sometimes cost an artist a lot of fans to be this courageous. That's one of the reasons why Katy Perry is so awesome.
