To the editor: Abbe R. Gluck claims that the loss of the filibuster is a "tragic loss for our democracy." In fact, getting rid of the Senate filibuster will allow us to regain some of the democratic principles of our government. Democracy requires that the majority legislates and governs, and the Senate is the most undemocratic part of our government. It is possible for 41 senators representing a small minority of the U.S. population to effectively shut down the government by preventing cloture. The Affordable Care Act was not an example of bipartisan cooperation.
