When we consider the question of whether Republicans can govern from Capitol Hill, the obvious first thought is that everything they want to do will ultimately come up against Barack Obama's veto pen. That's true, but so is this: The Congress is a co-equal branch of government with the Executive. Neither can really govern without the other. Obama can veto legislation but he can't pass it. Obama can make executive decisions (and clearly loves to do so), but he can't appropriate funds to pay for executive actions.
