The Presidential Showdown, Round II: Biden v. Ryan

Ryan: Biden is going to come 'flying' in debate (USA Today)

GOP vice presidential nominee Paul Ryan says he's ready for Joe Biden to come at him like a "cannonball" in their debate later this week.

"Because they had such a bad debate, Joe Biden is just going to come flying at us," Ryan told radio host Frank Beckmann on WJR in Detroit. "It seems pretty clear that their new strategy is just to call us liars, to descend into a mud pit."

Biden and Ryan will meet in their only debate on Thursday at Centre College in Danville, Ky. ABC's Martha Raddatz will moderate the event, which will feature questions on both domestic and foreign policy.

Ryan has been getting ready for the debate with the help of Ted Olson, a former solicitor general for President George W. Bush. Biden's debate partner has been Rep. Chris Van Hollen of Maryland, the top Democrat on the House Budget Committee that Ryan leads. CNN reported Obama adviser David Axelrod also sat in on some of the pre-debate sessions.

In the radio interview, Ryan called Biden a "gifted speaker" and "proven debater."
