At Thursday’s vice presidential debate in Danville, Kentucky, Vice President Joe Biden went all in, playing the traditional role of a vice presidential candidate: the attack dog. At times his answers played a little loose with the facts, as when he claimed that personnel at the U.S. consulate in Benghazi hadn’t asked for increased security, but he hewed far closer to the truth than Ryan, who once again trotted out the false claim that that administration is cutting Medicare, and again offered no details for how he would pay for the 20 percent across-the-board tax cut that the Republican campaign is proposing. Biden, however, had his facts and figures at the ready, as well with an evident disdain for the arguments of his opponent, Rep. Paul Ryan of Wisconsin.

During one exchange between the candidates over how close Iran was to obtaining a nuclear weapon, Biden took issue with Ryan's claim that Tehran closer to having an operable bomb than it was four years ago.
