On May 24, the California Senate passed SB 660, which outlaws paying initiative petition circulators on a per-signature basis. The vote was 28-11. All Republicans voted against it, and two Democrats, Senators Anna Caballero and Steven Glazer, also voted against it. In the past these bills have passed with no opposition from any Democratic legislators.
The last three Governors, Arnold Schwarzenegger, Jerry Brown, and Gavin Newsom, have always vetoed these bills.
