State Senator David Johnson, the only independent to serve in the Iowa legislature in recent decades, announced today he will not seek re-election in November. He had won four previous state Senate races as a Republican and indicated last year that he planned to run for another term. However, Johnson had neither raised nor spent any money from his campaign account since January 1.

The retirement gives the GOP, which already holds 29 of the 50 seats in the upper chamber, a clear shot at picking up Senate district 1 in the state’s northwest corner. According to the latest figures from the Iowa Secretary of State’s office, this district contains 7,304 active registered Democrats, 20,589 Republicans, and 13,333 no-party voters. Only one seat (nearby Senate district 2) is more heavily skewed toward the GOP. Brad Price, Zach Whiting, and Jesse Wolfe are competing for the GOP nomination in Johnson’s district. Democrats did not field a candidate here.
