The White House announced on Thursday that Biden will travel to the Port of Charleston in South Carolina to discuss jobs and infrastructure. Biden is also scheduled to visit the Port of Savannah, Georgia, later that day.
While the visit is an official vice presidential trip, South Carolina just happens to be another crucial early voting state, holding the first southern primary in the race for the White House. This will be Biden's second visit to the Palmetto State this year.
"You don't want South Carolinians to feel unloved," joked Rasky.
Besides visits to the early voting states, another indicator of whether Biden may launch another presidential bid will be his decision on whether to set up a leadership PAC. Such a move could signal that he is taking more of an interest in setting up a possible campaign structure.
A Biden political adviser, who asked to remain anonymous to speak more freely, said that a leadership PAC is "still being mulled over."
Speaking before Biden at the steak fry will be San Antonio Mayor Julian Castro, who's considered a rising young star in the party. Castro, who gave the keynote address at last year's Democratic convention, is also considered a possible 2016 contender.
Biden won't be the first sitting vice president to speak at Harkin's event. RadioIowa news director Kay Henderson points out that Vice President Al Gore was the main attraction at the 1995 and 1999 events, before running for president in the 2000 election.
