Replying to your edited bits:
And you know mid-terms will probably swing back the otehr way like they often do.
Remains to be seen, but it makes no difference in the House, and thanks to the GOP's fecktardery, the cushion the Dems have built up in the Senate should hold them through.
Obama and the GOP need to negotiate and get the budget passed. That is the number one priority not beating ones chest on side issue and party lines.
Obama has always been willing to negotiate. The GOP can't say the same. If the only thing they're willing to do is a bit of deduction-closing, but still insist on a nearly all-cuts budget, then it'd be better to let the sequester go through.
People are wise to the GOP's playbook. Let the GOP be the ones who sent the economy back into recession to save tax cuts above $250K. Those midterms'll look a lot better for the Democrats.
