To hear Barack Obama tell it, the federal government has been subsisting on a starvation diet in recent years. But then, that's the Keynesian liberal's excuse for why the economy isn't growing. Growth comes from federal spending in their universe, and even though we spent more than 20 percent of GDP during these so-called "austerity" years, it's never enough. So now Obama wants to spend us to the brink of $4 trillion, a record for federal outlays, in 2015.
