Assuming you don’t wish to enshrine “Democrats get a filibuster and Republcians don’t” into law, whatever rules you make you must be able to live with no matter who’s in charge.
My tone may have come as a reaction to the New York Times, which has openly switched back and forth between saying it’s “most important that a large minority of senators has a limited right of veto” and saying “We have supported eliminating the filibuster for judicial and executive nominees. Making other filibusters harder would be good for both parties. If Mr. Reid remains majority leader in January, he should lead the reform.”
