Senator urges Hillary Clinton to seek presidency

Hillary Clinton 'thinking' about 2016 White House run

Sunday was Clinton's first time back in the state since her defeat. "It's really great to be back," she said. "Let's not let another seven years go by."

Clinton, whom many Democrats consider the frontrunner for the 2016 race, made a series of missteps this summer while promoting her memoir. Clinton said she and Bill were "dead broke" when they left the White House, a comment that was roundly criticized as suggesting she was out of touch with everyday voters.

After a summer spent promoting her memoir across the world and relaxing in New York's tony Hamptons, the steak fry event marked the kickoff to a series of events in which she will campaign and raise money for fellow Democrats for the 2014 midterms. While Bill Clinton has campaigned for candidates this year, Hillary has stayed out of the fray up until now.

For decades, retiring Senator Harkin's steak fry has provided a platform for Democratic presidential hopefuls to introduce themselves to Iowans, including Obama, who attended the event in 2006.

Presidential candidates lavish attention on Iowa because of the importance of its nominating contest that comes at the beginning of the electoral calendar.

Many potential Republican contenders, including Kentucky Senator Rand Paul, Florida Senator Marco Rubio and Texas Senator Ted Cruz, have already visited the state, and possible Clinton rival Maryland Governor Martin O'Malley swung by earlier in Sept.

Vice-President Joe Biden, who has also hinted at a White House bid, plans to visit Des Moines on Wednesday. Vermont Senator Bernie Sanders, a self-described democratic socialist who is considering challenging Clinton from the left, stopped by the state on Saturday.
