Wasn’t it Obama that demanded sequestration? And wasn’t it Reid who tabled a bill passed by the GOP House that would avoid it?
Correct on both counts, but only the partial story to date.
Jack Lew, Obama's Office of Management and Budget (OMB) director came up with the idea of Sequestration. Bob Woodward confirmed this. Obama said during the final debate with Romney that it came out of Congress. That was a lie - but it was Congress that signed off - including the GOP.
The Republicans have passed two bills to avert Sequestration, but both had zero chance of passing the Senate. The Republicans were given three chances to turn off Sequestration during the Fiscal Cliff talks, and they turned each one of them down, shocking the Democrats and the White House. In fact, the media reported that the Republicans were walking out of the negotiation room after the tax deal was agreed to and it was the Democrats who had ask them to address it. In short, all their rhetoric during the campaign about diverting this appears to be hot air.
The GOP also said they would alleviate the Defense cuts through the Debt Ceiling negotiations, but they gave up that fight before they even tried, and then the GOP announced after their "retreat" meetings in Virginia (aptly named those), that they had "embraced" the Defense cuts.
