The next steps in detail but edited and formatted to make it easier to read 
If the Rs win the Motion to Proceed, we enter 20 hours of debate. Surreally, that's all the debate we'll get on Trumpcare.
In this case, though, the MTP isn't necessarily a preview of final vote because we won't know what the final bill will be.
Tue-Wed, we'll have 10 hours of R speeches, 10 hours of D speeches, furious dealmaking, & mega public outrage
Then vote-o-rama: the weird Senate thing on budget reconciliation bills where each side proposes unlimited amendments & ALL get voted on
Normally vote-o-rama is for "messaging" amendments in which each side proposes things that the other side will look bad voting against
This time, vote-o-rama will be used by Rs to propose radical restructurings of the health care system without time for debate or review
Meanwhile, Dems will, I hope and expect, come ready with 100s or 1000s of amendments to extend vote-o-rama as long as possible
Each amendment currently gets a 1 minute speech from each side and then a 10 minute vote. So voting on hundreds of amendments = grueling
That's the only way Ds can delay the final vote. But the Parliamentarian could rule them dilatory. Or McConnell can change rules anytime
So at some point, Parliamentarian or GOP will presumably shut down the process and move to final vote on... something.
At the end, McConnell will intro an amendment that wipes away all previous amendments. That's the final bill. Possibly unseen till then
And then the Senate will vote on Trumpcare, whatever Trumpcare is at that point. A mystery bill that could shape all of our futures.
Everything we've all been doing—millions of us calling, marching, sitting in, fighting for months on end—comes down to what a few Rs do
In a series of moments, each a second or two long, a handful of Republican senators will vote yay or nay—death or life for untold 1000s
If the Senate votes yes on Trumpcare, it's very likely that the House votes the bill through intact & with mind-blowing speed.
