The risk is that Republicans have a history of undermining their own. Granted, McCain was the leader in cobbling together "gangs" of "bipartisan" Senators to offer a "third way" that was really a Trojan Horse for the Democrats' way.
I'm just afraid that this tendency is still in the Republicans' DNA, and will tug hard on their resolve the longer this goes on. Flake was especially afflicted with the McCain curse; he's gone now but there are still weak-minded Republicans (Ben Sasse?) who will fall under the spell to be the "reasonable turncoat" who steps up to undermine the Republican base position, thinking they're doing what's best for "the American People," but really just advancing the liberal Democrat position.

“I’m just afraid that this tendency is still in the Republicans’ DNA, and will tug hard on their resolve the longer this goes on. “
I share your concern on this based on past GOPe performance, but it is very possible that the old playbook will be changed. Most of them know their futures are tied to Trump, whether they like it or not. The party as a whole has not embraced this outsider, Trump, who has to be more “independent” than GOP. If he were the latter, he would not have been elected. If this issue ends with a handful of GOPe voting against him, and more than a handful of democraps voting with him, then there are big cracks in the status quo. Change for the right reasons never comes easily, but let’s hope it comes for the betterment of this country. Merry Christmas “PJ Too”!
