Vice president Joe Biden and Republican Vice Presidential nominee Paul Ryan greeted each other warmly at the start of their only debate. But it didn't take long for the fireworks to begin.
Ryan: "When we look weak, our adversaries are much more willing to test us, they're much more brazen in their attacks."
Biden: With all due respect that's a bunch of malarkey... Because nothing he said is accurate.
Both candidates appeared engaged when speaking and when listening to their opponent... With vice president biden often smiling or laughing while Ryan was speaking.
The two squabbled over entitlement programs.
Ryan: Medicare and Social Security did so much for my own family, we are not going to jeopardize this program, but we have to save it.
Biden: You are jeopardizing the program, you are changing the program from a guaranteed benefit to premium support, whatever you call. The bottom line is people are going to have to pay more out of their pocket.
The stakes were high for both candidates heading into the debate. After last week's match-up, Mitt Romney gained ground on President Obama in the polls. .
The two sounded off on the biggest issue of the campaign, the economy.
Biden: They're holding hostage the middle class tax cut to the super wealthy.
Ryan.There aren't enough rich people and small businesses to tax to pay for all their spending.
Both candidates will take their messages on the road... Ryan has campaign appearances in Ohio, Biden will speak in Ryan's homestate of Wisconsin.
