I also realize that there are 22 R senate seats up for grabs in 2020 vs 12 D seats. Three are currently tossups - 2 Rs and 1 D.
We also have an election coming up where the winner MAY have two SCOTUS nominations to fill.
If I had to guess, McConnell (RINO-KY) and Trump have talked...Yertle is planning on a vote on the background check and red flag legislation, knowing has has the nay votes but would let tossups vote yea to win their re- election. That kills it. Or...In the end, Repubs delay until some other thing occupies the news cycle, and either the Senate votes it down, or it Trump vetos it.
Or think about this...Dems send Trump gun legislation - like an "assault weapons ban" on 12 scary guns. Trump gets them to be grandfathered and be 12 firearms where ample substitutes exist - but Trump attaches to the legislation full border wall funding and deportation.
How would we feel then? If Trump signs it, campaigns on continuing the building of The Wall maybe he beats Harris/Spartacus in the Electoral College AND popular vote, and we get 2 more conservatives on SCOTUS.
Yes, it sucks. But you can't always get what you want. Politics is ugly.
Oh, so to get the border secured, I have to give up my rights?
At ANY price.
