Only 26% of eligible Americans are unvaccinated, and that number is still shrinking every day. Yes, there is a depressing number of hardcore anti-vaxxers, but it's a much smaller minority than 35% of the population.
According to polls, one-third of the unvaccinated say they would get the shot if they were given time off work to deal with the symptoms. That suggests their "vaccine refusal" is related to their precarious economic circumstances and isn't a political stance. That brings the number of hardcore vaxxers down even further, to around 17%. This is probably still an overestimate, since some proportion of this population are minors and not making their own medical decisions, or may have other non-political reasons.
