And how, pray tell, would you suggest people "stop" him now?
Impeachment? Ya, right. Will never happen unless he gets caught on videotape molesting an elderly woman, while toking from a water bong and sporting a tattoo of Mao on his chest. Even then, I am doubtful the Hosue would Impeach.
And if they DID Impeach him, there is no way in hell the Senate would do anything beyond censure him and probably not even that much.
The problem with your assertion is that the SYSTEM is corrupt, not just this man.
And now he doesn't have to worry about re-election, since the snivelling masses have usurped American idealism.
So, again, how do you propose he be "stopped"?
