Bottom line -
Trump is still President for a guaranteed 2 months.. He has every right to do his job and fill that seat now while he's the standing President.. The Senate has that same duty as well..
You can't have only 8 supreme judges as you need 9 so you don't have a spit vote, especially when this up coming Presidential election is probably gonna be in legal dispute with voting fraud and what not one way or the other.
You need a fully commissioned Supreme Court panel of 9 as written in the Constitution!!
FILL IT and FILL IT NOW!!!
On a lighter note -
