Columbia resident Rick Wade, a senior advisor to Barack Obama's presidential campaigns and a cabinet officer for former Gov. Jim Hodges, said Friday that he is seeking the Democratic nomination next year for the U.S. Senate seat held by Republican Tim Scott of Charleston.

"The people of South Carolina understand that Washington is broken. If we are going to solve the big problems we face and get things done, our representatives must be accountable to their constituents," Wade said in a statement released by his campaign.

"That starts with three commitments: First and foremost, is the commitment to listen to the people, secondly, a promise to work for bipartisan solutions to fix our problems, and thirdly, a commitment to reduce the influence of special interests that have enjoyed too much power in Washington for too long," he said.

Richland County councilwoman Joyce Dickerson and businessman Jay Stamper also have announced Democratic senate bids, The State newspaper reported.

Scott was appointed by Gov. Nikki Haley last year to fill the vacancy left when Jim DeMint resigned.

Wade, 51,served as senior advisor and deputy chief of staff for U.S. Secretary of Commerce Gary Locke. He is a former executive at Hoffman-La Roche pharmaceutical company and Blue Cross Blue Shield. In the Hodges administration, he led the Department of Alcohol and Other Drug Abuse Services.

Wade graduated from the University of South Carolina and earned a master's degree in public administration at Harvard University where he was a Kennedy Fellow.
