“I think McSally will win. I hope she does. That’s the only shot that obviously Republicans have to hold on to the seat, but it’s even difficult then. This is going to be a hard-fought general election,” Flake told reporters.
Flake continued on AZ primary: "...and I think long term if we don’t appeal to a broader electorate and quit trying to drill down harder on the base and just you know give into the politics of anger and resentment, we’re gonna lose big time long term.”— Jason Donner (@jason_donner) August 28, 2018

McSally is facing off against two conservative firebrands, former state Sen. Kelli Ward and former Maricopa County Sheriff Joe Arpaio, for a chance to compete in the November general election for the seat being vacated by Flake.
All three candidates competing in Tuesday's Republican primary have tried to tie themselves closely to Trump, who has relationships with each of the candidates.

The winner of Tuesday's GOP primary is likely to face Democratic Rep. Kyrsten Sinema (Ariz.) in the fall. The three-term congresswoman is well-funded and has avoided a grueling and bitter primary.
A compilation of polls by RealClearPolitics shows Sinema leading all three GOP candidates in hypothetical matchups, but defeating McSally by the smallest margin of the three.
