Unlike the majority of his media colleagues, Charles Krauthammer understands President Obama’s approach to the debt-limit debate. Krauthammer shares his wisdom this morning with National Review Online readers:

President Obama assailed the lesser mortals who inhabit Congress for not having seriously dealt with a problem he had not dealt with at all, then scolded Congress for being even less responsible than his own children. They apparently get their homework done on time.

My compliments. But the Republican House did do its homework. It’s called a budget. It passed the House on April 15. The Democratic Senate has produced no budget. Not just this year, but for two years running. As for the schoolmaster-in-chief, he produced two 2012 budget facsimiles: The first (February) was a farce and the second (April) was empty, dismissed by the CBO as nothing but words untethered to real numbers.

Obama has run disastrous annual deficits of around $1.5 trillion while insisting for months on a “clean” debt-ceiling increase, (i.e. with no budget cuts at all). Yet suddenly he now rises to champion major long-term debt reduction, scorning any suggestions of a short-term debt-limit deal as can-kicking.

The flip-flop is transparently political. A short-term deal means another debt-ceiling fight before Election Day, a debate that would put Obama on the defensive and distract from the Mediscare campaign to which the Democrats are clinging to save them in 2012.

A clever strategy it is: Do nothing (see above); invite the Republicans to propose real debt reduction first; and when they do — voting for the Ryan budget and its now infamous and courageous Medicare reform — demagogue them to death.

And then up the ante by demanding Republican agreement to tax increases. So: First you get the GOP to seize the Left’s third rail by daring to lay a finger on entitlements. Then you demand the GOP seize the Right’s third rail by violating its no-tax pledge. A full-spectrum electrocution. Brilliant.
