I noticed every CA-SEN poll shows a decent chance of a D vs. R runoff, but CA-GOV always shows Newsom vs. Villaraigosa. How accurate is SurveyUSA/ABC in California.
FiveThirtyEight gives Survey USA a letter grade of 'A,' based on 763 polls analyzed, which puts them ahead of most of the crop (though the rankings haven't been updated since August 2016).
Their final poll of the 2016 senate race from mid-October had Kamala Harris up 21 points. She won by 23.
Their final 2016 presidential poll had Clinton +21, she won by 30.
