How many House Republicans can John Boehner drag along at the end of the day to support a budget deal that will have at least some revenues? Team Obama/Biden, to their credit, have never wavered on this, and that matters. They can't get their caucus behind them without revenues in the deal, because, as the president pointed out yesterday, no revenues would mean putting everything on the spending side of the ledger, and that would do far more harm than good, both to the economy and to the people in it. So, as has been the case all along, the debt ceiling negotiation all comes down to a numbers game, and I don't mean dollars, I mean votes.
