In a radio interview three days ahead of his debate against Vice President Biden, GOP vice presidential nominee Paul Ryan on Monday contended in some of his strongest language yet that Democrats are distorting his and Mitt Romney’s record on the issues.

“They’re just going to call us liars for a month, is basically what they’re going to do, it looks like. ... It seems pretty clear that their new strategy is basically just call us liars, to descend down into a mud pit and hopefully with enough mudslinging back and forth and distortion, people will get demoralized and then they can win by default; sort of a choice of the lesser or two evils,” Ryan told radio host Frank Beckmann on Monday morning.

Ryan, who called in to the radio show ahead of a Monday night event to Rochester, Mich., said that he and Romney believe that the Wolverine State is “absolutely” still in play even as most recent polls show Obama ahead by double digits.

Ryan also sought to raise the bar for Biden before Thursday’s face-off at Centre College in Danville, Ky., noting that Obama chief strategist David Axelrod has been spending time in recent debate sessions with the vice president.

“Obviously, what we expect is the vice president’s going to come at me like a cannonball,"  Ryan said. "They say that he won every single primary debate in 2008. So believe you me, I understand that this man is extremely experienced.” (Ryan was apparently referring to a comment made by MSNBC's Chuck Todd.)

Making note of Romney’s widely-hailed performance in last week’s presidential debate, Ryan said that his running-mate “definitely put the pressure on from that perspective.”
