When a progressive liberal says they want to pack the Supreme Court (and destroy the rule of law in the process) they mean it. It’s backed by white papers peddled by fancy think tanks. There’s like PACs backing it. The ideas are published by professors in reputable journals.
When MTG “likes” a juvenile comment saying “a bullet would be quicker,” obviously I don’t treat that with the same weight, because that’s a figurative phrase that doesn’t convey an actual plan to kill anybody.
I think it’s a fair thing for parties to have to defend the concrete policy proposals of their wings. Not so much random inane muttering of individual members.
