Sometimes I think Obama is trying to get impeached and thus reelected. If the nation again becomes fixated on an impeachment they will ignore his Marxist ideology and corruption, blatant attacks on the constitution, gun running to Mexico, refusal to control the border, and his appointments of socialist, Marxists and some ex communists (I do not think they are ex) to positions of great power in the government and the judiciary. They will also ignore his dismal failure in the creation of jobs.
It is my opinion that only two things can save the presidency of Obama.
1. Impeachment
2. Mitt Romney
Clinton was impeached two years into his second term in late 1998, but the Senate failed to remove him.
As far as gun running to Mexico, Holder better resign, or he'll be impeached, IMHO. That will put the Senate in a bit of a bind, except for states with safe rat seats. They have to defend 23 seats with 7 of them open next November.
