Dems, GOP fight brewing over curbing filibusters | Lubbock Online | Lubbock Avalanche-Journal WASHINGTON (AP) — A brewing and potentially bitter fight over Democratic efforts to curb*filibusters*is threatening to inflame partisan tensions in the Senate, even as President Barack Obama and Republicans explore whether they can compromise on top tier issues such as debt reduction and taxes. A potential showdown vote to limit Senate*filibusters*would not come until January. Democrats are threatening to resort to a seldom-used procedure that could let them change the rules without GOP support, all but inviting Republican retaliation. Republicans also note that in public remarks Reid made on the Senate floor in January 2011 during a discussion with McConnell, Reid agreed to oppose "any effort in this Congress or the next to change the Senate's rules other than through the regular order." That was a reference to Senate rules requiring two-thirds majorities for rules changes. Democrats say it is Republicans who broke the January 2011 informal deal the two leaders discussed because McConnell said he would use procedural delays "with discretion."
