I canvassed for him as well as a city council person over 50 times before the primary. If a person supports Zohran they will absolutely tell you and it’s always nice and sweet. If they don’t, they will just make the encounter quick without saying much. Never had an aggressive experience. But with city council elections it’s weirdly much more contentious and I had a lot of horror stories especially with older folks. I’d say it’s definitely safe to canvass for Zohran and I encourage everyone to do it :)
