Bob Vander Plaats, the standard-bearer for social and religious conservatives in Iowa, has announced he will not run for Iowa's open U.S. Senate seat.
Vander Plaats said in a written statement Saturday that the timing of a Senate run was not right for him, his family or his conservative advocacy group, The Family Leader.
He also said he didn't want to "compromise the message of my new book" with a campaign.
Vander Plaats ran unsuccessfully for governor three times as a Republican and orchestrated the 2010 campaign to oust three of the state Supreme Court justices who were part of the 2009 ruling legalizing same-sex marriage in Iowa.
At least six Republicans are vying for the seat being vacated by retiring Democratic Sen. Tom Harkin.
