"Where are the 5 million green jobs" we were told would be created? Ryan said to Biden.
Obama campaigned in Florida during the day. Mocking recent changes in Romney's rhetoric, he told a rally in Miami rally, "After running for more than a year in which he called himself severely conservative, Mitt Romney is trying to convince you that he was severely kidding."
Romney visited with 93-year-old Billy Graham in North Carolina before speaking to an evening rally in Asheville, N.C. "Prayer is the most helpful thing you can do for me," he told the evangelist.
For Biden, Thursday night's debate was his first since the 2008 campaign, when he shared a stage with Sarah Palin, then John McCain's running mate.
Ryan spars frequently with Democrats during debates on legislation on the House floor and in the House Budget Committee, which he chairs, but not in a one-on-one encounter covering 90 minutes and a virtually unlimited range of topics.
For all their differences, the two men shared a common objective, to advance the cause of their tickets in a close race for the presidency — and avoid a gaffe that might forever seal their place in the history of debates.
Romney's choice of Ryan as running mate over the summer cheered conservatives in the House, many of whom regard him as their leader on budget and economic issues. The seven-term lawmaker has authored a pair of deficit-reducing budgets in the past two years that call for spending cuts and changes in Medicare, blueprints that Republicans passed through the House and Obama and his allies in Congress frequently criticize. He also champions a no-tax increase approach to economic policy.
As a senator before becoming vice president, Biden was chairman of the Foreign Relations and Judiciary committees, and he has long experience in national security issues. More recently, he was Obama's point man in arduous, ultimately unsuccessful negotiations with Republicans on steps to cut the deficit.
