It is theoretically possible, though very doubtful IMO, that the House could impeach Obama.
There is not a hope in hell that the Senate would produce even a majority for conviction, much less 2/3.

I would offer that if any testimony from Petraeus is just so damning that it leaves no shadow of doubt that oblunder lied, covered up, watched Americans die with help available that was stood down and showed complete ineptitude, then it’s likely that there’s some senators especially the 20 up for re-election in 2014 would vote to convict. They won’t want to be tied to this in any way. They’d have the concession that they’d still have Biden (d) as president.
That all depends on what is discovered in the House. The fact that the Senate is under Dem control, will actually help the impeachment process get started. Dems will know that the only way Obama could be removed would be if half the Dem senators wanted him removed. And they might depending on what is discovered in the House. The next US Senate elections have more Dems then Pubs up for reelection.
