This is the one part about lifetime appointments… They don’t need to be loyal to Trump the second after they’re appointed. They don’t need to be loyal to anyone except their own judgement on the issues and Congress (which can in theory remove them if they have bad behavior).
They really don’t have any reason to not throw Trump to the wolves if the legal argument stacks up, unless there’s some other kick back going on behind the scenes, or they personally are a huge fan of Trump… Which maybe his own appointments are, at least most of them, but I don’t think the entire conservative block will join those guys and may very well side with the liberal block.
Still, I’m not going to hold my breath, and I fear the implications of this trial either way. The cleanest thing to do would be to just not vote for Trump and beat him in the ballot box. This feels both appropriate and underhanded in a way that might result in violence from the right… But maybe that’s just where we’re at.
