Aaron Blake in The Fix, on this Monmouth University poll, which finds:

Nearly two-thirds (65%) of the public say it is appropriate to describe the incident at the U.S. Capitol as a riot, and half (50%) say it is appropriate to describe it as an insurrection. Both of these numbers, though, are down from a year ago (by 7 points for riot and by 6 points for insurrection). These negative views of Jan. 6 have held relatively steady among Democrats and independents, but have slipped significantly among Republicans. Last year, a clear majority (62%) of Republicans called the incident a riot. Now, less than half (45%) do. Similarly, a third (33%) of Republicans in June 2021 said it was appropriate to describe the incident as an insurrection, but only 13% say the same today.

By comparison, the number of Americans who say it is appropriate to describe the U.S. Capitol incident as a legitimate protest has remained stable over the past year (34% now compared with 33% in June 2021). However, the number of Republicans who see this incident as a legitimate protest has actually risen by 14 points to 61%, at the same time this view has declined among independents (down 6 points to 33%) and remained stable among Democrats (14%).
