The fact that the Oakland NAACP doesn't want her either is kind of a hint that its not her race that's the problem.
I don't suppose you're actually curious about what has happened to the Oakland NAACP in recent years, and why they are now in lockstep with the Republican machine on most issues, not just this one. But if you are, you can learn more

I'm sure there are some people out there who legitimately hate Price for being a Progressive, not as such for her skin color or lack of rich jerk cred. Not everyone in the Bay Area is a "liberal", this is true. The leadership of the Oakland NAACP certainly is not, at present. But the place to hash that out was the fair and legal election in which Price was elected, not with this sham of a recall.
