Missouri Secretary of State Robin Carnahan says she will run for the U.S. Senate in 2010.
Carnahan, a Democrat, is the first candidate of either party to officially enter the race after Republican Sen. Kit Bond announced last month that he will not seek re-election.
She announced her candidacy today on her Web site.
Carnahan comes from a prominent political family. Her father, Mel Carnahan, was a two-term Missouri governor who died in a plane crash in October 2000 while campaigning for Senate. He won anyway, and her mother, Jean Carnahan, was appointed to the Senate seat but lost it two years later.
Carnahan's brother is St. Louis area Congressman Russ Carnahan.
