What is the easiest way to find out who voted against this bill so I can put them in my "don't vote for these people" list?
It's free to subscribe. But - IMO - it is likely that the OpenStates.org site monetizes the subscriber data somehow.
As far as CA-specific 'follow what a piece of legislation is doing' there's this site from the California state government: https://www.assembly.ca.gov/informationtohelpyoufollowthepro...
- Ayes (in favor), - Noes (against), - and No Vote Recorded (NVR; the equivalent of abstaining).
Looks like the [most recent committee vote referred in the article for SB 8](https://leginfo.legislature.ca.gov/faces/billVotesClient.xht...) is not online but will likely be by mid week.
