DES MOINES, Iowa (CNN) - In a new ad up in Iowa, Democratic presidential hopeful Joe Biden takes a swipe at fellow candidates Barack Obama and Hillary Clinton, saying that "when this campaign is over, political slogans like experience and change will mean absolutely nothing."
Clinton and Obama have been in a back-and-forth over which quality is most important, experience or change.
"The next president has to act," the Delaware senator continues in the ad, which began airing Tuesday in the Hawkeye State.
Biden, chairman of the Senate Foreign Relations Committee, also touts his plan on Iraq, and mentions that "when Pakistan erupted in crisis" he spoke with President Pervez Musharraf before President Bush.
"You don't have to guess what I'll do as president," Biden concludes. "Just look at what I've done."
The spot is his second in Iowa this year. The first went up in August.
On Monday, Biden said he plans on finishing in the top three in Iowa, which will pave his path to the nomination.
Biden was in fifth place in the most recent Mason-Dixon poll, released Sunday, with the support of 5 percent of Democratic caucus voters in Iowa.
