Treasury Secretary Jack Lew has notified Congress that the U.S. government will reach the limits of its ability to borrow in mid-October.  Lew’s letter sounds the opening notes of the overture to this fall’s fiscal grand opera. Between October 1 and the end of the calendar year, President Obama and Congress will battle over the debt limit, fiscal 2014 spending, and a fistful of expiring tax provisions. A dwindling few see this depressing confluence of fiscal deadlines as an opportunity to reach the long-awaited Grand Bargain. But in reality it is just the opposite, an excuse to avoid the tough choices of tax and entitlement reform. After all, it is easier for Washington to battle over self-made, short-term crises than resolve structural tax and spending challenges. If you are a Republican, it is easier to demand that the Affordable Care Act be defunded than to back tough, specific cuts to Medicare. If you are Democrat, it is easier to rail against the inequities of the sequester than kill government programs that don’t work. And if you are a politician of either party, it is much easier to embrace the vague concept of tax reform than to cut specific popular tax preferences. But having raised the profile of the great budget debate, lawmakers can’t just walk away from it. This is especially true for Republicans, who must somehow satisfy their tea party wing. But Democrats have something of the same problem with their left, weakened as that faction is these days.  So they need a distraction from the tough choices. What better diversion than a good headline-generating brawl.   While a handful of lawmakers seem serious about remaking fiscal policy, most have a different agenda: Saving face without doing much at all. Thus between now and New Year’s Day Washington will focus on trivia. Will the debt limit be extended for six months or a year? Will Congress fund 2014 agency budgets at sequester levels, Obama’s proposed levels, or something in the middle—an argument likely to center on about 1 percent of total federal spending? House Ways & Means Committee Chairman Dave Camp (R-MI) says that in October--in the midst of all that noise—he’ll propose his version of tax reform. In a healthy political environment, Camp’s plan would kick off a welcome debate over tax reform. But in the current dysfunctional atmosphere, it is likely to get lost in the cacophony. This will be too bad. But for many in Washington, replacing serious debate with loud short-term squabbles over phony fiscal crises is exactly the idea.
