Between Aug. 11 and Aug. 26, Survey Sampling International conducted the poll on behalf of UC Berkeley, sampling 1,098 respondents. Of those polled, 74 percent said local authorities should not be allowed to ignore federal detainer requests. The other 26 percent supported the sanctuary city policy of preventing local police and sheriffs officials from honoring immigration holds.
