- The upcoming debate is unofficial "Round II" between the two presidential campaigns
- CNN's Jessica Yellin: People will see if Biden makes up for Obama's performance last week
- Ryan, a statistics junkie, will come well prepared on policy, analysts say
(CNN) -- A former senator vs. a congressman. A Catholic vs. a Catholic. A policy wonk vs. an experienced speaker. The elements are in place for an interesting debate between Vice President Joe Biden and Rep. Paul Ryan.
And Sunday marked Round II of the expectations game, as campaign advisers and surrogates sought to set the stage for Thursday's showdown.
Republican National Committee Chairman Reince Priebus argued that while Ryan is known as a "smart" guy and will do a "great job," the vice president is no stranger to the debate spotlight, given his 36 years as a senator and two presidential runs.
"Joe Biden is a gifted orator. He is very good at rhetoric, and I think is he very relatable," Priebus said Sunday on CNN's "State of the Union."
"They are very two different people. And I think it's going to be a great night."
The two opposing running mates face off for their first and only debate at Centre College in Danville, Kentucky.
With Mitt Romney widely recognized as the winner of last week's debate -- the first of three match-ups for the presidential candidates -- some speculated Sunday whether the pressure was on Biden to blunt Romney's momentum and steal the mantle for the Democratic ticket.
"A lot of people will be tuning in to see how Vice President Biden tries to make up for the president's belly flop last week," CNN Chief White House Correspondent Jessica Yellin said on CNN's "State of the Union."
