You mean from 2012? Whitman will almost certainly flip from R to D, and depending on how bad it gets for Republicans, Spokane and Walla Walla could flip as well. Klickitat and Yakima could conceivably flip from D to R, but I doubt it.
I honestly wouldn’t be surprised if the GOP barely scrapes out in Benton and Franklin, for that matter.
I'd think Asotin (ancestral strength, she won it in 2006) and Kittitas (lost by 1.4%, CWU turn out should be high) would flip before those two.
I'd say Whitman and Spokane are all but guaranteed R to D flips. Cantwell only lost Spokane by 339 votes against local Baumgartner. Walla Walla would be next, it almost voted for Murray in 2016 (lost by 1.2%).
The key to holding Yakima (and over-performing to a lesser extent in Kittitas, Chelan, and Klickitat is to get the fruit grower/farmer (or whatever it's called) endorsement like she did in 2012.
