1. He participated in the effort to hold the debt ceiling "hostage" in 2011 that led to the eventual passage of the BCA. IMHO we wouldn't even be talking about a "sequester" if they had just raised the debt ceiling without demanding concessions for doing so.
2. He voted for the BCA as did most Republicans at the time. Those whom didn't refused largely b/c it didn't go FAR ENOUGH
3. The "Super Committee" went nowhere, largely b/c Republicans refused to agree to any new revenues
4. President Obama has put forward several proposals to cut spending but all of them were reflexively rejected by Republicans
5. The sequester was never really meant to happen in the first place. It was meant to be a leverage tool
6. Boehner is not working on any new proposals to eliminate/replace the sequester and has now abdicated his leadership role to the Senate
7. The sequester could easily be eliminated with a quick bill but see #6
Republicans have now basically decided to let the sequester happen and bank on President Obama and Democrats bearing the brunt of the fallout thereof, hence all of the current spin and maneuvering.
