Tradition of Politics
It should be obvious that the Senate compromise to avert filibuster was not about politics, not about bipartisanship, but about the preservation of the way the Senate does business. By this maneuver these "moderates" have proposed that the filibuster is a legitimate Senate tool, but should be preserved for "special" circumstances. The real significance has little to do with the filibuster itself but that a group of senators acting not on political ideology have made a successful power brokerage. I'd much rather see politicians acting political to advance their political ideology rather than to leverage power without ideology, or worse, to preserve "business as usual".
