A 2016 Maricopa County primary election ballot.

Some races from this week’s primary are still too close to call, including the GOP contest in the 5th Congressional District, and the Republican race for Maricopa County Recorder.

To try to figure out why the primaries shook out the way they did, and what that means for November, KJZZ talked to  Garrett Archer, a data consultant at Integrated Web Strategies. Starting next week, he’ll be the assistant director of Election Information Systems in the Arizona Secretary of State’s Office.
