Vaccinated people, as a whole, seemed to hear the message. Earlier this month, just 37% of fully vaccinated adults said they were always wearing a mask when they were outside of their house. We didn't see the same drop among the unvaccinated over the same period. A nearly equal 36% of this group indicated in June they were always wearing a mask when they were outside of their house. Still, the partisan gap is very present. Only 20% of fully vaccinated Republicans said they were always wearing a mask when they go out. Among Democrats, it was 48%. The size of this partisan difference (nearly 30 points) is pretty much the same as it was a month ago, even as the percentage of both fully vaccinated Democrats and Republicans always wearing masks dropped. This gets at something that has been shown in other polling: Democrats tend to overestimate the threat of Covid-19, while Republicans tend to underestimate it.
