The filibuster rule change only applies to the toadies Obama wants to place in positions of power, not bills themselves (Yet) - However, I Do suspect that if the Dems do lose the Senate, they <<WILL>> ditch all filibuster rules via simple majority and ram everything through they possibly can. Then shortly before the current congress ends, the Dems will vote to restore filibuster rules via the same 51% majority.
That won't work, and here's why. The filibuster rules only last for the two years fo whatever Congress is in session. If the Republicans wanted to, they could adopt the same filibuster rules as the Dems did, then see how the Dems like their medicine. Mitch McConnell has already said that he will
not do this. I'd like to see Rubio, Cruz, or Rand Paul become the Majority Leader and tell both the RINOs and the Dems, "Time for your medicine."
