NASHVILLE, Tenn. (AP) _ Longtime Sen. Douglas Henry says his health and the high cost of campaigning were factors in his decision not to seek re-election next year.

The 86-year-old Nashville Democrat officially met with reporters on Wednesday. His political ally attorney sent an email to Henry's supporters last week announcing his decision.

Henry said he had been disregarding his doctor's request that he not run again but finally decided to take his advice. He also said the amount of money he spent on his 2010 election was ``obscene.''

That year, Henry narrowly beat a 33-year-old Nashville attorney in the Democratic primary. A recount gave Henry a 17-vote win.

Henry's District 21 seat represents southwestern Nashville, including some of the city's wealthiest neighborhoods.
