I think you are correct. Romney coat tails will help the GOP retake the Senate and add to the house, thus helping Romney not having to reach across the aisle.
Romney needs to remember all of the vile stuff the democrats have said about him and play hardball when he gets to the white house.
The Republican majority leaders also need to play hardball;their history is of caving and crying.Gingrich is the only Republican Congressial leader to really push the conservative way.
