State Sen. Kelly Townsend announced Friday she is withdrawing from the race for the Republican nomination for Arizona's new 6th Congressional District because former President Donald Trump hasn't endorsed her. Despite encouragement and repeated assurances, “the promised formal endorsement has still not materialized," leaving her unable to unify the conservative vote in the August primary, Townsend said in a statement. Townsend said she knew a Trump endorsement might be jeopardized by her recent criticism of state Sen. Wendy Rogers. Rogers has already been endorsed by Trump in her re-election race. Townsend didn't refer to Rogers by name in her statement.
