Carmona is seen favorably by a 13/12 spread even by Republicans, probably owing to his past as a Bush appointee, and he gets 10% of the GOP vote against Flake. That's more crossover support than we've been seeing for most Democrats in the last few years. Flake takes 12% of the Democratic vote though, and has an early 29-26 lead with independents.
Carmona's early competitiveness has a lot to do with strong support from Hispanic voters. He leads Flake 56-19 with them in his bid to become the state's first Hispanic Senator.
