1. They believe that because they control both houses of Congress, they can do whatever they want or, more importantly, President Obama should just sign everything they pass because they do(assuming it makes it to him in the first place). Bush vetoed a lot of things that a Democratic Congress sent him from 2007-2009. Get over it.
2. They believe that President Obama should (and will) voluntarily destroy his own signature achievements (i.e. ACA). Sorry, guys (and some gals), only somebody out of his/her mind would voluntarily sign legislation destroying their own achievements. Not.gonna.happen.
3. Adding "poison pill" riders to bills, while totally legal, is not a recipe for getting legislation passed and when it comes to having to pass "must-pass" legislation to fund the government, it's an especially bad idea and they're going to have to cave on it eventually, so why waste everybody's time?
4. Demanding that "a majority of the majority" support something (in the House) or a supermajority in the House before even bringing it to a vote is extremely undemocratic and isn't to be found in the Constitution anywhere. The more you insist on passing things in this way is going to ensure a lot of time wasted on things that might not pass in the Senate and will be DOA on President Obama's desk if it somehow makes it there. The House and Senate were NOT designed to work in this way!
