Vice President Joe Biden will be in Iowa on Sunday, which will once again trigger speculation he may make a run for the White House in 2016. Biden will headline the annual steak fry put on by longtime Democratic Sen. Tom Harkin. The event, which dates nearly four decades, is one of the signature events for Iowa Democrats, drawing top politicians, and it has a rich history of attracting presidential hopefuls. Biden has not said whether he'll make a third run for the Democratic presidential nomination. He launched unsuccessful bids in 1988 and 2008. "I can die a happy man never having been president of the United States of America. But it doesn't mean I won't run," Biden said in a July interview with GQ magazine.
