Here’s an idea for what can be done, provided that the GOP wins enough seats: a Constitutional amendment to repeal every bill passed since January 1, 2009. Obama can’t do anything about it since the President plays no part in the passage of a Constitutional amendment. The trick would be getting 37 states to ratify. By my count, 22 states would definitely ratify, and 9 definitely would not. So it would be close, but it would be something that Obama could not stop, at least not directly.
