That's easy. We need both houses of Congress. And not just Republican control, but conservative control. They can stand up to him and prevent his "walking around Congress.' But even if it is Romney we still need a conservative Congress and control of both houses to keep him in check as well.
I agree with your last sentence, but all the conservative congress members in the world will not stop FUBO. He takes pleasure in doing what he sees as the will of the rest of the world and overriding his own country’s voice.
He has effectively negated our elections, since he treads right over our legitimately elected officials.
