Can you provide examples of a Republican controlled senate appointing a liberal judge and a Democrat controlled senate appointing a conservative judge?
Was RBG a moderate? Was Scalia? What about Thomas?
I think the idea that the Supreme Court was always full of moderates before Trump and that Coney Barratt and Kavanaugh are some extreme cases is, politely, absolutely bonkers.
Ruth Bader Ginsberg was voted in 96-3. Scalia was voted in 98-0.
And you're trying to compare them to who, Amy Coney Barrett? 52-48. Kavanaugh? 50-48?
This is entirely the point. The way everyone before McConnell/Trump handled supreme court nominations is that you nominated someone who would get bipartisan support, because they might lean left or right, but they were proper, respectable judges.
They weren't fundamentalist catholics with 2 years experience as a judge who think contraception should be banned.
If you can't see the difference you are being wilfully stupid.
