I am flat out not interested but just to play along:
What does "selected" mean? Selected to then be reviewed and approved by the Senate? - or y'all are going to amend the constitution along the way?
I would imagine a constitutional amendment would be needed. I can’t really see how adding a level of consent and/or removing one would be legal under the current constitution.
I think the spirit of the idea is well intentioned. Nobody likes partisan decisions and funny business in the senate.
But this all goes back to the misguided idea to directly elect senators. It really makes no sense for the intended structure of congress.
