It comes down to this:
Despite his reelection, Obama is not King of America. Neither was Bush II nor Clinton.
America is designed to have representation for taxation discussions. Districts can send a nutty 'tea party' candidate to Washington just the same as they can send someone as mentally imbalanced as Alan Grayson to serve as their representative. These people represent citizens in their districts and require certain provisions to be met before they sign on to any deal. Obama, Biden, Boehner, Reid Pelosi and McConnell go behind closed doors to design a deal and people are surprised when elected representatives won't vote for it? shocking.
Boehner is absolutely right to quit negotiating directly with Obama. Let the House go through procedures to craft a bill that can pass that chamber then send it to the Senate. Get a bill that both chambers agree on, and Obama can't get away with voting 'present' anymore.
The welfare of humanity is always the alibi of tyrants
