IRA STOLL: Four big takeaways from the second night of the Democratic National Convention. Including this: “Steny Hoyer faulted Paul Ryan for having ‘voted to put two wars on the credit card.’ Chris Van Hollen, another House Democrat, also faulted Republicans for the cost of ‘two wars’ and ‘a new entitlement,’ presumably a reference to the Medicare prescription drug benefit. But hardly any Democrats opposed the war in Afghanistan, and President Obama, when he came into office, increased the troop commitment there. ObamaCare also makes the prescription drug benefit more expensive (to the federal government, not to seniors) by reducing the so-called doughnut hole range for which seniors must pay the cost of some drugs. It seems a little inconsistent to blame the Republicans alone for these components of the debt or deficit.”
