WASHINGTON Rep. C.W. "Bill" Young, Fla., the longest-serving Republican in Congress, announced that he won't be running for a 23rd term in the U.S. House.

Young, 82, will end his congressional career after his current two-year term ends in January, 2015, said spokesman Harry Glenn.

"It's my time" to leave Congress, Young said in an interview with the Tampa Bay Times from Walter Reed National Military Medical Center, where he's recovering from a back injury.

"I don't know that I would pick out one thing. It's a lot of things. My family, my job, my rehabilitation from my back," he said.

Partisan gridlock also was a factor, Young told the newspaper. "I'm a little disappointed," he said. "It seems there's too much politics. It's a different Congress."

First elected in 1970, he's been an advocate for increased government spending on medical care, from boosting immunization rates to increasing research on Parkinson's and Alzheimer's diseases. In 1986, he helped create a national registry for bone-marrow donors a program now named for him.

He was chairman of the Appropriations Committee from 1999-2005, and never hesitated to point out that was the last time the government ran a surplus.

He represents a district that includes Clearwater and most of St. Petersburg, Fla. In 2012, the constituents who returned him to office also backed President Barack Obama, 50 percent to 49 percent, making it one of just 17 districts nationwide that year that voted for Obama and a Republican congressman. Democrats need a 17-seat gain for a majority and surely will be targeting this district in 2014.
