LIVE BY RECONCILIATION, DIE BY RECONCILIATION: Senate Republicans just introduced an Obamacare repeal plan Democrats can’t stop.

Senate Budget Committee Chair Michael Enzi (R-WY) introduced a budget resolution Tuesday that includes “reconciliation instructions” that enable Congress to repeal Obamacare with a simple Senate majority. Passing a budget resolution that includes those instructions will mean that the legislation can pass through the budget reconciliation process, in which bills cannot be filibustered.

That means Republicans will only need 50 of their 52 members in the Senate, and a bare majority in the House, to pass legislation repealing the Affordable Care Act. According to the Wall Street Journal, the budget resolution could be passed by both houses as early as next week.

To be clear, passing the budget resolutions does not itself repeal Obamacare. But it’s the necessary first step if Republicans are to do that this year, and unless three or more Republican senators defect (or 24 House members do), it’ll be smooth sailing for the repeal effort from there on out.
