A Berkeley Institute of Government Studies poll puts California Governor Gavin Newsom (R) at 46% for a job approval rating, down from about 66% in September. A Public Policy poll has him at 52%.
The IGS poll has a 49% opposed to a recall and 36% seeing it as good, with 45%-36% opposing the recall.
For whatever it's worth, Newsom seemed to outperform the polls in 2018, when he got 62% of the vote. The polls for his opponent (John Cox) seemed more on point.
