You are not going to find a credible source that says "Obama is evil" I think he is a God awful President and I do not think he is evil. But if you look at mainstream sources and reputable conservative/libertarian sources (like reason, National Review, and the like), you will find tons of stuff about the mess that is ObamaCare, the IRS scandal, the NSA scandal, the BS "most transparent administration in history", the wiretaps of news agencies, the illegal NLRB appointees, crap economic policy, more and more government waste, a march towards more government dependency, etc.
With all that said, there are a few things he has done that I have liked (not worth the bad, but they exist)
I found all that mostly from politico, news.google.com, thehill.com, and realpolitics.com (which features good op-ed writers). I do not need obamaisevil.com
Read the facts and then you can determine what you think of Obama (or anyone else) versus however you came to the conclusion Obama is evil .. which I would be interested to know how that came about.
