The candidates' itinerary and rhetoric was a microcosm of their contest, with McSally trying to keep the state's traditional GOP voters in her column while Sinema tried to cast herself as a nonpartisan problem solver only incidentally attached to the Democratic party.
McSally was joined by the entire statewide GOP ticket, from Gov. Doug Ducey on down, as she tried to remind Arizona Republicans to continue their decade-long stint of winning every statewide race.
"You guys are my wingmen and my wingwomen," McSally, a former combat pilot, said to supporters at a stop in Flagstaff. "And the only way we're going to get victory tomorrow is if everybody digs deep, everybody does their part. You can sleep in 32 hours."
Sinema handed out doughnuts at the downtown Phoenix campus of Arizona State University, high-fiving voters, posing for selfies and exchanging hugs with longtime friends -- she teaches at the school and has four degrees from there.
