WASHINGTON -- Vice President Joe Biden on Monday told Iowans that he knows their state well from campaigning there as a former presidential candidate, a bid that didn't work out quite as planned.

"On the way on the plane, to show you how effective I am, my political guy said I'm glad we've got your schedule for just the last time around when I was trying to get the nomination," Biden said during a campaign pit stop at Good Earth Restaurant in Muscatine, Iowa, according to pool reports.

"I spent 120 days in Iowa. You saw how effective I am. You know what I mean?" he said. "But I'm a good vice president."

An older woman at one of the tables responded, "You haven't done too bad."
