Worth noting: up until 2016, it was not unusual at all for the state to have competitive races. Rs narrowly lost in 2004, 2008, and 2012 - running well above the top of the ticket each time. And the 2010 Senate race was also close, within five points. https://twitter.com/jmilescoleman/status/1384682755569684482

If Rs could unite their previous suburban support with new WWC gains in the coastal regions, they could be competitive in statewide races. However, the suburbs appear to be long gone and the WWC areas simply aren’t enough to do much with.

Oregon was also unusually competitive in 2000 and 2004, and it routinely has competitive gubernatorial races. Dems haven’t gotten more than 50.7% in a gubernatorial race since 1998, and Rs held a senate seat as recently as 2008.
