tell them to what? not vote for a democrat, their own party, to replace a supreme court justice?
your contention is that manchin and sinema will leave the seat open for 3 years?
they didnt "block voting rights". they refused to blow up the filibuster, because there's a very real chance that the republicans control all 3 branches of government in under 3 years
i would think you understand that. and given most of the discourse in here, you would have a healthy fear of that
and what exactly is the correlation between not signing onto a massive spending bill in the middle of high inflation, and refusing to seat your own party's supreme court justice?
you have to break out of this mindset that anyone to the right of bernie sanders isn't a real democrat
