You might have read the recent news about Joe Lieberman’s efforts to block meaningful health care reform. It’s no longer surprising that Senator Lieberman is doing everything he can to slow down or stop reform, but it might be surprising to know that his efforts have been opposed by . . . Joe Lieberman.

Yes, just a few years ago, Senator Joe Lieberman testified in support of legislation offered by Senator Joe Lieberman to stop the kind of maneuvering that Senator Joe Lieberman is doing right now.

In late 1994, I joined Senator Harkin in launching an effort to encourage Senate discussion of reforming the Senate’s cloture rule. Like Senator Harkin, I had become increasingly frustrated at the way the Senate’s cloture rule repeatedly allowed a minority of Members to prevent the Senate’s majority from enacting legislation. I felt–and continue to feel–that the Senate rules should be changed to prevent a small minority of Senators from bringing legislation to a halt simply by saying that they will never end debate. Senator Harkin and I therefore offered a proposal under which an initial cloture vote would require 60 votes, but the requisite number to reach cloture would decline by three with each of the next three cloture attempts on the same matter. As of the fourth cloture vote, 51 votes–a simple majority–would suffice to invoke cloture.

Yes, Senator Lieberman was deeply concerned by abuse of the filibuster. But apparently times have changed. Since Democratic activists booted him from the party, Senator Lieberman has reversed himself on any number of major issues for no discernable reason beyond political expediency. (NB: This is what Senator John McCain calls “principle.”)
