Huge? Probably 52 in the Senate, possibly 54. That is not huge, and can be filibustered into obscurity.
And with a veto from O, it means little. Then in 2016, when Demographics have made the GOP gerrymandering of little affect, the table will turn 180 degrees. We are living in historic times. First we see the first Black President and then we see the first Woman President. WOW!
Good thing for the Republicans that Democrats limited filibuster power, isn't it?
