Clinton's strategy might be to let voters get their revenge against the Democrats in 2014 so that in 2016 it will be a level playing field. It would not matter to her that if she won in 2016 Congress was controlled by the Republicans. She doesn't have an agenda anyway, as evidenced by her lack of accomplishment as SoS. It is more important to her to be something than do something.
She might set a goal for herself of trying to break the million mile mark on AF1 in her first four years.
