FT says this

As it stands today, the US borrows about 40 cents of every dollar it spends. Curbing the budget deficit has been the stated mission of Mr Ryan, a rising Republican star, for several years. But such calls for action have multiplied in Washington in recent months, igniting what some say is the fiercest debate over fiscal and budgetary policy in decades.
The risks are big. If the government rushes into austerity, cutting too much and too quickly, it could stunt economic recovery. But if the political system cannot forge some kind of consensus on steps to restore US deficits to sustainable levels, the danger is potentially even greater: a sovereign debt crisis in the world’s largest economy.

Don't worry about too little government spending, even the Tea party will have a problem spending too little.
