Here’s what’s going to happen. These 13 Republican white men will write a bill that screws over the American public similar to how the House bill will.
And then it will fail. No Democrat will vote for it. Senators Collins and Murkowski won’t vote for it if it defunds Planned Parenthood or makes insurance unaffordable for those with pre-existing conditions. The Senate will need every single other Republican (plus Mike Pence to break a tie) in order to pass anything resembling what the House barely passed. And it’s doubtful they will get that. Especially as the CBO report on the House bill will probably be released before anything comes to a Senate vote.
