WASHINGTON -- No, the sun didn't rise in the west this morning. No, Republicans on the congressional supercommittee didn't offer meaningful concessions on raising new tax revenue. And no, "both sides" are not equally responsible for the failure to compromise.

As usual, the two parties began with vastly different ideas of what it means to negotiate. Democrats envisioned meeting somewhere in the middle, while Republicans anticipated not moving an inch. This isn't just my spin, it's a matter of public record: Before the 12-member supercommittee ever met, House Speaker John Boehner warned that it had better not agree to any new tax revenue.
