Rep. Stephanie Herseth Sandlin (D) announced Tuesday on her Web site that she plans to run for re-election, therefore ruling out a statewide bid for either governor or Senate in 2010.

“I wanted you to be among the first to know that today I am announcing my intention to run for re-election to the U.S. House of Representatives in 2010,— Herseth Sandlin wrote.

She cited work on implementing the farm bill and her co-chairmanship of the Blue Dog Coalition among her reasons for staying in the House.

She told Roll Call earlier this year that she had not ruled out running statewide and would make a final decision this summer.
