As the Wall Street Journal points out:
"Asked about raising taxes on the middle class on Sunday on CBS’s 'Face the Nation,' White House economist Larry Summers wouldn’t repeat Mr. Obama’s pre-election promise. 'It is never a good idea to absolutely rule things out no matter what,' Mr. Summers said—except, apparently, when his boss is running for office. Meanwhile, on ABC’s 'This Week,' Treasury Secretary Timothy Geithner also slid around Mr. Obama’s vow and said, 'We have to bring these deficits down very dramatically. And that’s going to require some very hard choices.'
"These aren’t even nondenial denials. The Obama advisers are laying the groundwork for taxing the middle class while claiming the deficit made them do it."
