“If I’m missing anything in this analysis, let me know”
As mentioned earlier in this thread, Obamacare and Harry Reid dodged a filibuster by passing the bill through budget reconciliation, a parliamentary maneuver which only requires a simple majority.
Trump now has that simple majority, so he will simply repeal Obamacare, root and branch.
With the “Democrat” Illinois and New Hampshire senators now gone, that will be much easier.
