Seems like this might be dead in the water anyway and beyond GOP Senators control at all unless they can get several Dems to vote for it (good luck!). Seems there's basically zero chance they can get 60 votes in the Senate with only 53 GOP members and 2 independents and from what it sounds like a few GOP Senators that are already saying they won't vote for it. That means the Senate Parliamentarian as the mediator has the power to remove anything she deems is not related directly to the budget under the Byrd Rule to pass with a a simple 51 vote simple majority. "Under this rule, every provision must have a clear and direct impact on federal spending or revenue. Measures considered "merely incidental" to budgetary outcomes, or those that stray into policy-making, are prohibited. " The Senate can of course overrule her, but they'd need 60 votes which also seems pretty unlikely.
One could make a case that removing the $200 tax impacts the budget directly, but it might be hard to say it's a significant impact to the budget at about $12 million in revenue per year in a budget of $6.8 Trillion, that's about 0.00017%.
Hopefully I'm wrong but this sure seems like another case of politicians tacking something onto a big bill they know has zero chance of actually staying intact and passing so they can tell their voters they gave it their best shot.
