No but the Senate makes its own rules, and one of those rules is a tradition of unlimited debate. Until there are no objectors or a super majority agree the discussion should be terminated, legislation cannot be voted on.
For decades now minority parities have leveraged this to block the bodies business when it is doing something they don't like.
It is possible for the majority to simple 'change the rules' but nobody really wants to do that because they know the shoe will be on the other foot in another election cycle or two and don't want be railroaded when its there turn.
So the 60 vote majority requirement persists, as removing it is basically a mutually assured destruction situation, that will hold until one party feels they are certain to have a sustained comfortable majority going forward - I expect. The moment that happens and if said party has anything hovering right around that 60 mark which could become 59 or whatever the rule will be eliminated so fast your head will spin - I also expect.
