Do you understand what you are saying here? The Republicans hold 53 seats in the Senate, out of 100. Four GOP Senators have decided to vote no. What would you have the Republican Party or Senator McConnell do about it? Collins, Murkowski, and Paul are not conservatives and are only Republicans because it's convenient for them. They are both Democrats and Liberals in all but label. And yes, I know that Paul claims to be a Libertarian. Just like Nancy Pelosi is a Libertarian, LOL.
Remove them from their high-level committee memberships ... assign them to the equivalent of a being-sent-to-Siberia committee and let them rot there. Cut off party funds to them for reelection funds, government perks, and legislative pork-projects
If they change parties as a result, at least there'll be some honesty in their truth-in-packaging ...
The number is apparently up to TEN Republican senators. Screw the GOP.
