Future Supreme Court justices

[UncleSam]

Democrats shouldn't worry about future nominations because as long as McConnell is in charge of the Senate they won't get a chance to make a replacement. He'll wait 4-8 years.

Nah, if it is RBG in the first two years of a Dem president McConnell would for sure allow a vote on a replacement. He might insist on someone older (like Garland) but even then I think Dems could tell him to stuff it and still get enough crossover support to get a reasonably replacement through.
