DANVILLE, Ky. – At odds early and often, Vice President Joe Biden and Republican Paul Ryan squabbled over the economy, taxes, Medicare and more Thursday night in a contentious, interruption-filled debate. “That is a bunch of malarkey,” the vice president retorted after a particularly tough Ryan attack on the administration’s foreign policy.

“I know you’re under a lot of duress to make up for lost ground, but I think people would be better served if we don’t interrupt each other,” Ryan later scolded his rival, referring to Democratic pressure on Biden to make up for President Barack Obama’s listless performance in last week’s debate with Mitt Romney.

There was nothing listless this time as the 69-year-old Biden sat next to the 42-year old Wisconsin congressman on a stage at Centre College in Kentucky.
