I think Republicans are pretty happy with the current filibuster limitations, since they get everything they want and can use it to block most everything Democrats want. Democrats tend to want to pass legislation to solve problems. Republicans want to pack the judiciary and keep the status quo.

But certainly. the second a majority Republican government wants to pass something, the filibuster is dead.

We're flying electric helicopters on Mars yet you can't turn on your clothes dryer in Texas. That's because scientists are in charge of Mars, and Republicans are in charge of Texas.
