Republican Sen. Martha McSally and Democratic challenger Mark Kelly meet Tuesday in what's likely to be the only debate of the race between the two combat veterans.
McSally will look to gain ground on Kelly, who has consistently led the race in polling and fundraising. In-person early voting in Arizona begins Wednesday and election officials around the state will begin dropping absentee ballots in the mail the same day.
TV spending in both the presidential and Senate races is smashing records, reflecting reliably red Arizona’s new status as a swing state.
