State of the Midterms: Sinema, McSally trade lead in final charge to Election Day

With just one day until voters cast their midterm ballots, Arizona's Senate battle remains one of the tightest races on the map -- with Republican nominee Martha McSally and Democratic rival Kyrsten Sinema trading the lead in the final burst of polling.

McSally, R-Ariz., held onto a 1-point lead in an ABC 15 poll, but an Emerson College survey gave a 1-point edge to Sinema. Both surveys put the race within the margin of error, underscoring how unpredictable the race has been for weeks. The Real Clear Politics average shows Sinema with just over a 1-point lead.

As with many states, though, a huge chunk of the electorate has already voted thanks to early or absentee voting. According to the Arizona Secretary of State’s office, nearly 80 percent of the ballots cast for the election will have been filled out before Tuesday’s election.

“The work we’re doing over these last five days is to communicate with voters who have not turned in their early ballot,” Sinema told reporters in Phoenix last week. “I’m just working hard to earn the vote and the support of Arizona.”

McSally spent the weekend hitting the stump. She is slated to campaign with Arizona Gov. Doug Ducey, who is running for a second term. A Fox News Poll released last week had Ducey with an 18-point lead over Democrat David Garcia, among likely voters.
