I know a number of Republican voters who were uneasy about her, because they still watch local TV - which was constantly calling her the most radical of right-wing Trumpists. I’m not sure how they voted, but it would not surprise me if some of them didn’t cast a ballot for the Governor’s race. Kimberly Yee (R) got 200K more votes for the State Treasurer office than Lake got - and she won easily. I’m sure 200K Republicans did not leave their ballots blank at the top and much cheating did occur, but there was some real Republican voter resistance to Lake.
This widespread cheating couldn't be sustained without tacit and/or active approval of the GOP establishment.
They would rather have a Democrat win than a MAGA Republican. They demonstrated that with their reaction to the Tea Party insurgency.
