[Verginius Rufus]

Reid probably thinks the Democrats will have a majority in the Senate forever, but if a miracle happened and the Republicans won enough seats to have a majority in the next Congress, the Senate could change the rules back (to requiring 60 votes) before the new Congress met.

The newly Republican led Senate on the first day of business can vote to rescind the 60 vote requirement; easy peasy (Can not bind a future Congress) if that sissy fight evolves.
