For an improbable fifth straight election cycle, Arizonans will once again vote for a U.S. senator. This time the race is for the successor to Sen. Kyrsten Sinema, I-Ariz., who announced in March she would not seek a second six-year term.

U.S. Rep. Ruben Gallego, D-Ariz., is the only prominent Democrat running from his party. Former TV broadcaster and gubernatorial candidate Kari Lake is running against Pinal County Sheriff Mark Lamb for the Republican nomination.

Before Sinema bowed out, Arizona faced the prospect of an unprecedented three-way contest. Now, the race figures to be a conventional two-way battle race and one of the more fiercely contested in the country.

The Arizona Republic is closely covering this important race. Here is our most recent coverage:
