I mean yes he should have been impeached 7-8 years ago, I mean now there is basically no point because he is out of office in less then two weeks. But to be honest I don't see any good candidate that's running. Clinton? Nope! Whatever that other guys name was? Nope!
He hasn't broke a law or misuse his power in any realistic way. There would be no reason to impeach him other then the problem that most people have with Obama (Black Liberal if i have to spell it out for you). Everyone who wants Obama impeached is because of those two reasons.
