If you look at the map the Democrats have a tough time. Manchin is done so WVA will have two senators now. Florida is now deep red. Same with Montana. Not sure the Democrats have a clear path anymore and if the GOP run a sane candidate in AZ they could take one of those seats. NV is very close too.The Senate fluctuates depending on who has to defend the most seats.
I believe that if one party manages to win the House, Senate and White House they have earned the right to pass their agenda
