Republicans were justifiably upset when they controlled the U.S. Senate and Democrats filibustered bills and judicial appointments. But now that they are in the minority, the GOP senators have doubled down on filibustering — literally. In the 108th and 109th sessions of Congress, 2003-06, Democrats filed cloture motions 68 and 62 times, respectively. After the GOP became the minority in the 110th session, 2007-08, it filed 139 cloture motions. And so far this current session of Congress, the GOP has filibustered at least 119 times, including blocking a Defense Department authorization bill last week. Bob Edgar, president of Common Cause, complained: "Deliberation and debate have given way to complete obstruction, all at the expense of American voters."
