'impeachment is off the table'.
pelosi knew that going at bush would only get him sympathy from moderates. the same way lewinsky rescued clinton - they did all that over a BJ?
All it would take is for a teary-eyed Obama to take the stand admit he only faked the birth cert "because I just love america that damn much!".... and look out! His ass would be at 70% approval rating, he'd waltz off as his endorsed Hilary replacement destroys the Gop offering.
better to let us all know it - backroom deal that he resigns for whatever reason - and never let him have that moment of redemption with the american people.
