This Daily Beast post is pretty devastating:
As the first year of the Obama era draws to a close, the president is losing the battle for America's hearts and minds. It's hard not to feel some sympathy for him, given the disastrous state of the economy when he took office and the many smoldering international crises that keep flaring up. President Obama's predecessors deserve plenty of blame for his woes—as Obama and his advisers never tire of reminding us. But their not-so-subtle digs at President George W. Bush paper over their own unforced errors . . .
It is certainly possible that President Obama is finally getting the hang of the most difficult job in the world. The question is whether or not it's too late."
