Tea Party true believers may be salivating at the prospect of the coming Battle of the Debt Ceiling, but the GOP’s leaders are dreading it. Shutting down the government is a button they dare not press – not if they retain the least grip on reality. They did it once before, during the Clinton administration, and were slammed: the shutdown rescued the Clinton presidency. To do it in 2011, with the economy laid low and financial markets still twitchy, would be the limit of irresponsibility. It would be betting the recovery to make a point. This time, political annihilation might follow, and the party would deserve it.
