The only thing that could sink Congressional Republican approval ratings even lower would be if they moved to impeach President Obama. So, naturally:

Rep. Michele Bachmann (R-Minn.) said Tuesday that President Obama has “committed impeachable offenses” and that the House could hold a hearing to impeach.

“We can have an impeachment hearing in the House, and in my mind the president has committed impeachable offenses,” Bachmann told conservative talk show host Rusty Humphries in an interview first detailed by Right Wing Watch.

Say what you want about Michele Bachmann, but I think "in my mind the president has committed impeachable offenses" is maybe the most honest thing she's ever said. In her mind, the president has done a whole bunch of things.
