Senate Seat, Tim Johnson To Retire http://apr.org/post/gop-eyes-sd-senate-seat-tim-johnson-retire South Dakota Senator Tim Johnson says he will not seek a fourth term in the U.S. Senate. The Democrat has served in Washington since winning the lone House seat in 1986. The decision thrills Republican in the state who see a chance to pick up a seat. Democrats are hoping they can field a strong enough candidate to prevent that. Wed, 27 Mar 2013 09:09:00 +0000 Cara Hetland 27438 at http://apr.org
