Arizona’s primary election day is underway.
With Sen. Jeff Flake deciding not to run for re-election, three Republicans and two Democrats are fighting for his seat. Not only are voters choosing who will represent their respective parties in races for the lone Senate seat, they are also selecting candidates for governor and several other positions.
Just one hour into Tuesday morning's voting, issues at polls across the Valley began being reported .
Here’s everything you need to know ahead of voting day.
What are the big races?
For the Senate seat, there are a number of Republicans running in the primary. Former Maricopa County Sheriff Joe Arpaio, U.S. Rep. Martha McSally, and former state Sen. Kelli Ward are fighting for their respective parties, while Kyrsten Sinema and Deedra Abboud are running for the Democratic Party.
Two of Arizona's nine congressional seats are wide open this year. All nine congressional seats are up for office; five are currently held by Republicans. Two seats -- the one held by Democratic. Rep. Kyrsten Sinema and the one held by Republican Rep. Martha McSally -- have no incumbent running.
Looking at the governor’s race, Republican Doug Ducey takes aim at a second term against challenger Ken Bennett. Steve Farley, David Garcia and Kelly Fryer are all vying for the Democratic Party’s seat.
The incumbent is the heavy favorite in that race, but polling shows a tight battle shaping up for the general election.
