In a Tuesday, Oct. 17, 2017 photo, former Republican Arizona state Sen. Kelli Ward smiles as she is greeted by supporters at a campaign fundraiser, in Scottsdale, Ariz. Ward was expected to run against Republican U.S. Sen. Jeff Flake in the Arizona 2018 primary, but Flake has bowed out of a re-election, announcing his retirement on Tuesday. Flake's decision to bow out of a re-election fight could spur a rush of other Republican candidates who hope to take on his only announced challenger in the Arizona primary next year.
