The political attention of the nation will turn to the desert on Tuesday evening as Arizona holds its primary elections in the triple-digit summer heat. Here are the key races to watch in the Copper State. On the Republican side, Kari Lake is expected to emerge from a primary race against Mark Lamb, the Pinal County sheriff. Ms. Lake’s scorched-earth governor’s campaign divided Republicans in Arizona, and she is still working to mend fences within the party. But she is favored to defeat Sheriff Lamb, a right-wing candidate who has made tougher border restrictions a centerpiece of his campaign.
