I find it interesting that you are telling me what I need to do to "make my legacy" and be successful. I AM successful and have done NONE of the things you suggest.
My goal for the next 4 years is to regain control of both houses of Congress by allowing a fiscal melt down and blaming it on the Republicans. I will force Republicans to agree to tax increases on the top half (who are their supporters) and more benefits for the bottom half (my supporters), in fact I hope to have the bottom 70% receiving government jobs or benefits in the next 4 years.
I will start interviewing candidates to replace me in January and I will hand the presidency to them in 4 years. How could I possibly be more succesful?
