The Clinton team is assessing trends in Arizona to determine whether to make greater investments here, and officials were cagey when asked to detail their strategy. In a statement, Marlon Marshall, the director of state campaigns and political engagement, stuck to the Clinton campaign’s national talking points: “We’re hearing real doubts from voters in Arizona about Donald Trump’s plans for a deportation force and his dangerous agenda on national security.”

Clinton’s footprint appears to be greater than Trump’s. His state director, Charles Munoz, is based in Nevada, and a visit last week to Trump headquarters in Mesa revealed little evidence of an active campaign. There was one worker eating lunch at his desk, a roomful of empty cubicles and, other than a small pile of plastic yard signs, no Trump paraphernalia, brochures or flyers. The GOP’s coordinated campaign has only one staffer, though party officials boast of an active volunteer corps and plans to soon open 14 offices.

Trump campaign and Republican officials argue that carrying Arizona is pure Clinton fantasy.

“Arizona will stay red,” Arizona Republican Party Chairman Robert Graham declared. “The progressive left should avoid the state of Arizona because it’s a bad investment.”
