mal really is ignorant of or deceitful about US government:
* In Congress, the House and Senate are almost equals; the House has no say in ratifying treaties or approving Presidential nominees, including judges;
* The President and Congress are equals, neither being able to act without the other - the President cannot write laws, and the Congress cannot enforce laws.
So winning control of the House is a big deal, just nowhere near as big as mal is trying to hype it into being.
