Arizona voters headed to the polls Tuesday to choose nominees in four key primary elections: Senate, governor, and two House races.

The most closely watched race was the Republican primary for the Senate seat vacated by retiring Sen. Jeff Flake between Rep. Martha McSally, Kelli Ward, and former Maricopa County Sheriff Joe Arpaio.

On Tuesday night, McSally prevailed with relative ease, setting up a November showdown with Democrat Kyrsten Sinema.

There’s also a competitive Democratic primary for governor to see who will challenge Republican incumbent Doug Ducey and two House races — including one where Democrats Ann Kirkpatrick and Matt Heinz are fighting bitterly.
