Republican Arizona Senate candidate Blake Masters has broken into the lead against Democrat Mark Kelly, according to new polls.

A new poll from InsiderAdvantage/Fox 10 News has Masters and Kelly tied. At the same time, the final poll of the cycle from Emerson College showed Masters with a slight lead; another poll from Big Data Poll found another lead for Masters. The polls come amid growing optimism for a Republican wave with just four days to go before the 2022 midterms.

The InsiderAdvantage/Fox 10 poll of 550 likely voters, taken on November 2, showed Masters and Kelly tied at 48% apiece. Libertarian candidate Marc Victor, who dropped out of the race and endorsed Masters on November 1, still took 2% of the vote. Another 2% were undecided.

InsiderAdvantage pollster Matt Towery told the outlet that Masters garnered support from more voters who identified themselves as independent. But the poll also found Kelly siphoning some 15% of self-identifying Republicans off from Masters.
