Jonathan Chait on his TNR blog:
Last Spring, Republicans threatened to shut down the federal government in order to force domestic spending cuts. House Speaker John Boehner managed to ass a bill. But a subsequent CBO analysis found the immediate savings were quite small. Conservatives went ballistic and vowed they won’t get fooled again.
I know, he meant “pass a bill.” But “ass” sounds better, and is actually a more accurate description of what happened.
