Gee, the Presidents approval rating is at 30%. Why don't I join the dogpile on top of him? Yeah that'll win me some points with him and help me get my agenda passed.
Note to James Dobson, we live in a democracy. If the president doesn't have enough popular support, he can't do anything. If you actually want to get your agenda passed, now is the time distinguish yourself by helping him. Help him do something right for a change. Otherwise you are just further cementing yourself in the role of perennial political malcontent.
