CA, OR and WA, while forevermore chained to the floor of the democrat plantation, are still fertile ground for fundraising and each state has a small handful of competitive House seats, so once the primaries are finished, the GOP nominee shouldn’t ignore them altogether.
The key is keeping those three states in perspective and not to harbor delusional thoughts about them somehow being “in play” in a Presidential election year, because they aren’t.
You are right.
There are strong pockets of voters for the GOP in these states, and they’re straining on the chain to help out.
