PPP’s newest poll of the Republican primary for the Senate in Arizona finds a clear leader- Blake Masters tops the field at 29% to 15% for Mark Brnovich, 10% for Jim Lamon, and 5% for Michael McGuire. This represents quite a shift in the field compared to March. Masters was in 3rd then with 13%, while Brnovich and Lamon were essentially tied for the lead then at 24% and 22% respectively. Since then they’ve seen their support drop by 9-12 points while Masters has nearly doubled his.
The ascendancy of Masters once again shows the Trump effect in a Republican Senate primary. 53% of GOP voters say they’re more likely to vote for Masters because he has Trump’s endorsement, while only 20% say that makes them less likely to support him. Trump has a 75/18 favorability rating within the GOP electorate and among the voters with a favorable opinion of him Masters has 35% with his main opponents coming in at just 11-12%.
Masters easily has the best favorability rating in the field at +18 (38/20). Brnovich comes in at +4 (28/24) and Lamon is actually under water at -3 (21/24).
