His politics.
1. He promises a whole bunch of stuff. Not only does he just not do it, but instead of changing it he does more of what he campaigned against. Gonna end the war? Lets continue it, bomb Libya, and fund it with taxpayer money.
2. Most of the "policies" are blamed on Obama. Unfairly of course. The stimulus bill was completely STUPID yet he approved it. Along with other wasteful spending, i feel that the government is really fucked up during his term.
3. The Nobel Peace prize. He literally did nothing and got it. Pretty much saying to anyone else who got it "hey, its not worth shit".
4. He is great at giving speeches, yet he doesn't do a lot for the country. I mean in all honesty he isn't improving anything, and he isn't doing what he said he would either.
Who wants a guy who doesn't even do what he said he would?
