Former Indiana Sen. Dan Coats plans to announce Wednesday that he will challenge Democratic Sen. Evan Bayh in November, a senior Republican official told POLITICO.
Coats held the seat Bayh currently occupies for 10 years before retiring in 1998. Since leaving Congress, he has worked as a lobbyist and served as U.S. ambassador to Germany during the George W. Bush administration.
"Coats deciding to run is a product of the environment we're in right now," the GOP official said. "This is a great opportunity for us. We have a real player on the field that they weren't expecting us to have."
Former Rep. John Hostettler and state Sen. Marlin Stutzman are already in the race on the Republican side.
