If they change the bill, it goes back to the Senate.
There are no planned changes to the Senate Bill. They have two bills they are planning on. The first is an in toto passing of the Senate bill which immediately gets signed into law. The second bill is the “cover” with proposed changes voted on by the House. There is NO obligation on the Senate to even consider the House bill. As Krauthammer says, you have a better chance believing in Peter Pan than in believing that the Senate will make ANY changes once their bill becomes “law”.
