What these critics routinely fail to mention (and too many reporters fail to report) is the precipitating action: the Democratic majority’s repeated use of a once-rare procedural gimmick that has kept Republicans from amending bills that are brought to the floor. This practice, known as “filling the amendment tree,” leads to a question that answers itself: Why would Republicans vote for action on a bill that, we’ve been promised, we’ll be blocked from contributing to in any way? If the majority wants more cooperation, it could start by allowing differing views to be heard.

Over the past four years, Democrats have used such gimmicks to pursue their most prized legislative goals while attempting to minimize the number of uncomfortable votes they’ve had to take. My Democratic counterpart in the Senate, Harry Reid, has played quarterback, setting records for the number of times he has blocked Republicans from having any input on bills, cut off our right to debate and bypassed the committee process in order to write bills behind closed doors…

A change in the rules by a bare majority aimed at benefiting Democrats today could just as easily be used to benefit Republicans tomorrow. Do Democrats really want to create a situation where, two or four or six years from now, they are suddenly powerless to prevent Republicans from overturning legislation they themselves worked so hard to enact?
