So fighting on the budget is what we should have been focused on all along. It's obvious that this Republican wish list isn't going to get through the Senate and past the president, but that's also not the end of the story. I wrote in my link above from last November:
Complicating this is the Republican threat to de-fund health care reform. I could easily seeing the Republican controlled House passing a budget that both de-funds health care and prohibits spending money to enforce the Clean Air Act. They will then attempt horse-trading, and I fear the concession that they'll ask for.
And yes, the Republican House did de-fund health care in the continuing resolution from this last week. We'll see who blinks on a potential shutdown versus a compromise and what gets sacrificed in a compromise.
