"Our position has not changed. Any debt limit increase would require cuts and reforms of a greater amount," said Boehner spokesman Brendan Buck.But Boehner is showing flexibility on how quickly to implement any increase in the Medicare eligibility age, recognizing the Democratic opposition to the idea. Republicans have been cautious on that front as well; they have regularly exempted those close to retirement age from their Medicare cuts. Obama originally sought $1.6 trillion in new tax revenue over a decade and has since revised that to $1.4 trillion. He would probably go lower, a decision fueled in part by resistance from Democratic allies in the Senate to Obama proposals like taxing capital gains and income at rates equal to earned income.
