Agriculture Secretary Tom Vilsack will not seek Iowa's open Senate seat, according to the Des Moines Register.
"He will not seek the open seat," Matt Paul, a Vilsack aide, told the Register.
Sen. Tom Harkin, D-Iowa, who has served in the Senate since 1985, announced his retirement last month, opening up a Democratic seat in the state.
Despite speculation about Vilsack possibly running in 2014, Vilsack, who was governor of Iowa from 1999-2007 and briefly flirted with a 2008 presidential bid, had not actually expressed publicly he was interested in the seat.
In light of his decision, Rep. Bruce Braley, D-Iowa, who has already announced his bid for the seat, currently appears poised to pick up the Democratic nomination.
