Controversial Arizona Sheriff Seeks to Oust Moderate Democrat in Senate Race

Mark Lamb, a right-wing ally of former President Trump, hopes to tap into voter frustration over immigration and runoffs in challenging Senator Kyrsten Sinema.
The 2024 race is shaping up to be deeply polarizing and expensive, with control of the Senate at stake.
Lamb faces a difficult primary but has significant support from the pro-Trump wing of the Republican party.
Sinema has not announced if she will seek reelection, but at least one Democrat is ready to challenge her from the left if she does.
