You do understand how the veto process works, right? Congress sends up a bill that the president has said he will veto. He vetoes, which sends it back to Congress. Without the necessary two-thirds majority, the override fails, putting it back on Congress to pass a bill that the president will sign.
I have no idea what you're talking about here. Both Boehner and McConnell understand that they don't have the required number of votes to override a presidential veto, and they aren't willing to shut down the government just to demonstrate to the Tea Party idiots that they don't have the votes to override a presidential veto, meaning that they would have to pass something the president will sign in order to keep the government open anyway, so why not do it and avoid a shutdown? At one time both Congress and the White House viewed a government shutdown as an embarrassing failure. So I don't know why you think it would be a good thing to pass something that's going to be vetoed. If they had the required two-thirds to override I could see it, but if a frog had a parachute he wouldn't bust his *** on every hop. Maybe those idiots learned something with yesterday's 77-19 vote in the Senate, but I doubt it.
