I think it was the NPR political podcast that mentioned the possibility of Senate Democrats letting Trump's nominee in but doing what Republicans did to Merrick Garland for any others. Maybe it is better to follow their example instead of blocking it up front. Let the people decide in the November 2020 elections!
I don't think that works all that well... A better idea is to get maybe Schumer or Warren in front of the cameras and say that "Maybe we should let the next President decide who's on the Supreme Court. It works well with 8 members for now." Cruz said it was fine back in October. So, you know what? I think Dems should say fuck it.
