Everyone seems to be dropping. Notice that Rasmussen has his worst numbers for the GOP in his generic ballot poll in over a year, and the GOP seems to be cratering at the state level.
Things are out of control, the Republicans have proposed extremely unpopular solutions, and Obama has proposed no solutions. Obama is tanking because he has shown no leadership, and when the entire world(Libya, Gas) is going out of control thats bad for the incumbent.
Yeah, the public seems to be in a foul mood, and that's not exactly an exclusive American phenomenon. Just look how unpopular are Sarkozy, Merkel, Cameron, Berlusconi, Zapatero, etc.
The entire world seems to be in turmoil.
