Not so sure this is a good idea.
I wonder if getting rid of the filibuster is along the lines of finishing off the Sinate, work that began with the 17thA.
No filibuster makes the Sinate just another House, and this would be the final straw.
The Sinate is indeed broken, but I think the proper fix is repeal of the 17th, to turn it back into a Senate. That means it will take awhile, and needs a Convention of States to accomplish.
Slippery slope to eliminate the Electoral College.
Its not going to happen, what will happen is more ranting against McConnell and Ryan. But Trump's OK, the master negotiator apparently got rolled.
McConnell wouldn't have the votes to do this and the GOP in the Senate will not replace him with someone who will.
First, historical lore says that the filibuster was part of the original design of the Senate. Not true. When we scour early Senate history, we discover that the filibuster was created by mistake.

You are correct that this would destroy the Senate.
I think the better idea would be to abolish the 17th Amendment and then get rid of the fillibuster.
Then the GOP would have 66 seats in the Senate
