Here's the reality that President Trump and Republican leaders are facing: They want to repeal Obamacare, but not the popular parts of Obamacare. But to the most conservative Republicans, and their supporters, repeal means repeal — which includes everything, whether it's popular or not.
That's why Trump and GOP leaders haven't been able to close the deal with the Freedom Caucus, and will have to try to steamroller them with today's vote. It's why they have the Koch brothers after them. And it's why, barring a miraculous turnaround, they're not getting any closer to a deal that can survive the Senate as well as the House.
