Medved has some good social values to be sure! But he is very poorly informed as to many political matters, it seems.
Congress (specifically the House) has the power of the purse.
no matter what Medved may think, this is how our government is set up
We were taught that in seventh grade civics and it is true. However the larger picture is more complicated. Advocates for various elements put pressure on House members wherever they're vulnerable. Vulnerable to a primary? We'll run somebody against you. Your biggest supporter is agriculture? We'll put pressure on them with a farm bill and they'll put pressure on you. Have something you'd rather not be made public? We have all your phone calls recorded and text messages. Oh, and that Tweet of your penis you did under your assumed name...nice.
