FYI, I had the same problem. I got no response from Google when I asked about it here (glad you got one.) So, I asked at Tech and Civic Life (who provides the data) and they apparently have data before Google gets it. Still, they were kind of slow to respond, so I switched over to BallotPedia, where I could actually see it in their app. Heads-up that both of those providers have revenue-sharing models if you want to use their APIs or data. Google probably does too, once you get over a certain rate limit.
Hope it helps.
