Yes. The only way to shut off debate in the Senate is to have 60 votes for cloture.
It's amazing just how the h*ll the Democrats have been able to slam-dunk the issues important to them in the face of a level playing field.
There has been NOTHING to suggest that were the GOP to gain a 60 vote majority that ANYTHING would be different. IOW, the GOP would still cower in fear at the sight on the Drunken Swimmer from Massachusetts.
