Arizona will be in the national spotlight in November as a presidential battleground and the home of one of the most closely watched Senate contests in the country. But Tuesday's primary on Aug. 4 features few big-ticket contests. McSally faces a challenge from businessman Daniel McCarthy, who is running to her right with an anti-government message and an appeal to voters who think the response to the pandemic is infringing on individual freedoms.
