I would rather stick it out for the next 2.5 years with Obama as an incompetent, increasingly ineffectual, lame-duck than risk having a 'president -- Joe -- Biden' and the possibility he might get "reelected" in 2012.
Furthermore, if Obama were to resign or be impeached any time after 2 years and 1 day in to his term, or the potential would exist (and however unlikely it might be I would not want to risk it) for us to have to live with almost SIX years of 'president -- Joe -- Biden'.
But, if we grit our teeth, oppose Obama every time he is wrong, and let him continue to fail then we can be rid of both of them in 2012.
I understand what you are saying but they can impeach him, putting him on trial in front of America, but not remove him from office. Like they did with Clinton. By doing this it would bring out everything he has done to ruin our country. Once he is impeached, I would think he would be powerless.
