INDIANOLA, Iowa (AP) — Hillary Rodham Clinton has returned to Iowa for the first time since her 2008 presidential campaign, telling Democrats that voters face a choice between "the guardians of gridlock" and those who push for shared opportunity and prosperity.

Former President Bill Clinton joined the former Secretary of State to pay tribute to retiring Iowa Sen. Tom Harkin at his final steak fry fundraiser. The couple arrived as anticipation was building over the possibility of another Hillary Clinton presidential campaign.

The former New York senator and first lady did not directly address a potential campaign but said she was "thinking about it." She joked she was "here for the steak."

Sunday's event drew more than 6,000 party activists who form the backbone of Iowa's presidential campaigns every four years.
