In the right environment, a moderate Charlie Baker or Phil Scott type could do it - Rob McKenna in 2016 or Knute Buehler in 2014, especially if either seat was open. Washington and Oregon aren’t quite as gone at the statewide level as California or New York.
Agreed. Buehler would have mopped up in 2014, and could arguably have come within 3-4 in 2016 (a neutral year, compared to D+7 2018). It's also worth noting that Oregon elected Republican (and sadly late) Dennis Richardson to the SoS office in 2016.
