Where I am in Canada, we typically do not prioritize canvassing neighbourhoods with more renters as they usually don’t vote.
I imagine that tenant rights and rent control transform many renters into essentially homeowners for purposes beyond the asset itself. They also aren’t impacted by prices.
I was told by a lawyer who does eviction cases that most jury members in SF are renters. My guess is that most who show up for jury duty also vote. There are consequences in theory for shirking jury duty, but my experience (from the early 1990s) was that the risk of actually incurring any consequences is very low.
