Imperial County is right of the state at this election; also it seems likely the exit poll will probably end up fairly accurate once all the votes are counted.
It obviously doesn't mean a "total political realignment" since this map really isn't meaningfully different from 2016/2018.
Exit polls look like they are going to be way off. They projected an about 18 point NO win and the real number will likely be in the mid 20's (NO +28 currently).
The story in Imperial is not the margin (currently within a point of 2018) but the horrible turnout.
