Senate Leaders at Work on Plan to Avert Automatic Cuts WASHINGTON - Senate leaders are closing in on a path for dealing with the "fiscal cliff" facing the country in January, opting to try to use a postelection session of Congress to reach agreement on a comprehensive deficit reduction deal rather than a short-term solution. Senate Democrats and Republicans remain far apart on the details, and House Republicans continue to resist any discussion of tax increases. But lawmakers and aides say that a bipartisan group of senators is coalescing around an ambitious three-step process to avert a series of automatic tax increases and deep spending cuts. First, senators would come to an agreement on a deficit reduction target - likely to be around $4 trillion over 10 years - to be reached through revenue raised by an overhaul of the tax code, savings from changes to social programs like Medicare and Social Security, and cuts to federal programs. Once the framework is approved, lawmakers would vote on expedited instructions to relevant Congressional committees to draft the details over six months to a year. If those efforts failed, another plan would take effect, probably a close derivative of the proposal by President Obama's fiscal commission led by Erskine B. Bowles, the Clinton White House chief of staff, and former Senator Alan K. Simpson of Wyoming, a Republican. Those recommendations included changes to Social Security, broad cuts in federal programs and actions that would lower tax rates over all but eliminate or pare enough deductions and credits to yield as much as $2 trillion in additional revenue. Finally, they would vote to put off the automatic spending cuts, known as sequestration, and tax increases scheduled to hit all at once in January - but with some deficit reduction down payment to signal how serious Congress is. Mr. Obama has said he would not allow Congress to simply pass a new law to override the $1 trillion in automatic cuts agreed to in the Budget Control Act of 2011, but senators said they believed the White House would go along with a deal that locks in as much as four times those savings in exchange for canceling the automatic cuts. With both sides awaiting the outcome of the election, negotiators will not even try to determine how much money would come from the three components until after the voting, when, presumably, the victorious side would emerge with new leverage. "A lot of what happens and when it happens depends on the outcome of the election," said Senator Mitch McConnell of Kentucky, the Republican leader. House Republicans, favored to retain control regardless of the presidential and Senate results, have not been part of the Senate talks so far and could be difficult to sway to back a package with significant new revenue even if it wins bipartisan Senate support. Democratic leaders are already signaling a major stumbling block: they will accept no deal that extends Bush-era tax cuts for the rich, even for six months. "President Obama has clearly stated he will not extend the Bush tax cuts for millionaires and billionaires, and I fully support his position," Senator Harry Reid of Nevada, the majority leader, said in a statement. Americans are sick and tired of simply kicking the can down the road and avoiding our nation's financial issues. Other senators, like Lindsey Graham, Republican of South Carolina, have counseled a more incremental approach to head off mandatory deep military cuts next year. Senator Richard J. Durbin of Illinois, the second-ranking Democrat, had suggested finding enough savings for a six-month delay on taxes and cuts to give negotiators more time. But Mr. McConnell compared the government to a ship sinking under the weight of Medicare and Social Security and said that temporarily holding off the automatic budget cuts and tax increases would not avert a disaster. "Even if we rearrange the chairs, fix the tax thing, fix the sequester, the ship's still going down," he said in an interview. I want to deal with it altogether. The next best opportunity is the end of the year. With their party leaders's encouragement, Senators Michael Bennet, Democrat of Colorado, and Lamar Alexander, Republican of Tennessee, have begun talks on legislative language to lock a deficit reduction framework into law.
