Fought the Vice Presidential Debate between Joe Biden and Paul Ryan

In a battle of substitutes, Vice President Joe Biden and Republican challenger Paul Ryan repeatedly clashed Thursday in topics ranging from the fate of Medicare until the terrorist attack on U.S. diplomats in Libya.

Both men were aggressive, eager to praise the strengths of their agendas and equally zealous attack their opponents.

Ryan was aggressive from the start, defying early versions of the attacks in Libya that offered the Obama administration, which initially said an anti-Muslim video ignited a crowd, instead of calling it a terrorist attack. He added that President Obama referred to the video six times in a speech to the United Nations after the attack on Libya.

"This becomes a bigger problem every day," Ryan said of the details still emerging from what the administration knew in those first days after the attack. Ryan said it was "an indicator of a larger problem ... the disintegration of the Obama foreign policy."

Biden defended the administration's response, saying it was based on intelligence that proved false. "Get to the bottom of it," he added.

Ryan, a federal agent had never debated nationally, despite his 14 years in Congress, showed no signs of nervousness during the confrontation with Biden, a veteran of 36 years of debate in the Senate.

Their confrontation, which was nationally televised from Centre College, was moderated by Martha Raddatz, ABC. The candidates were seated at a table, answering questions about national and international politics, the same format used by the vice presidential candidates Dick Cheney and Joe Lieberman when discussed in the same college in 2000. The format, as in an interview Sunday program, is to produce more conversational exchanges.

Discussions of the vice presidential candidates usually have little effect on the election, but on Thursday had added significance after Obama opaque debut in the 3 October.

Since then, Romney is tied with Obama in national polls and closed the gap in several swing states.

In Florida, Romney established a seven-point lead, according to a survey Tampa Bay Times / Bay News 9/Miami Herald. Obama has a lead of one percentage point over Romney in a new poll of likely voters NBC / Wall Street Journal / Marist released Thursday. The margin is the same before the debate Obama-Romney. In Ohio, Obama liderea by 6 points. In Virginia, Obama was 2, but now Romney forward by 1.

With only scheduled debate between them, Biden and Ryan transited over and over domestic policy to international.

Biden used a question about the unemployment rate in the nation to criticize Romney's comments recorded in the blasts which 47 percent of Americans as dependent not taxpayers. Biden accused Romney of having said that the foreclosure would get to the bottom.
