Vice President Biden and his Republican opponent, Rep. Paul Ryan of Wisconsin, had a lively debate at Centre College in Danville, Ky., this evening — one marked by Biden's aggressive challenges to many of the Republican vice presidential nominee's claims and Ryan's oft-repeated message that the Obama-Biden administration's policies aren't working.

The discussion was steered by ABC News' Martha Raddatz. It's the only vice presidential debate of the campaign.

It may be the undercard to the main event, but partisans on both sides are talking some trash ahead of the vice presidential debate tonight in Danville, Ky.

The pressure is particularly intense on Vice President Joe Biden, following his boss' lackluster performance in last week's presidential debate, which moved GOP nominee Mitt Romney into a national polling lead.

Tonight, Vice President Joe Biden and Rep. Paul Ryan are set for a one-on-one, 90-minute debate in Danville, Ky. It's the one and only VP candidate debate of the campaign and after what has been conclusively deemed a bad performance by President Obama during the first presidential debate, all eyes are on Biden.
