NASHVILLE, Tenn. (AP) -- Democrat announced today he won't run for the U.S. Senate seat now held by Republican Lamar Alexander.
McWherter, the son of former Governor Ned McWherter, said he has fundraising concerns and worries about the effects the race would have on his family.
The Jackson businessman had formed an exploratory committee in September.
The 51-year-old McWherter practiced law in Nashville until his father was elected governor in 1986, and then moved to Jackson to run his family's beer distribution business. He has two children in high school.
Former Democratic Party Chairman Bob Tuke and Nashville insurance lawyer Kevin Doherty, who had both agreed to defer to a McWherter candidacy, said they will have to decide quickly whether to get into the race.
Alexander, meanwhile, has no challengers for his party's nomination.
