The folks at the rally were motivated Trump supporters, virtually all of them other than media and security. Apparently, MOST did not go to the Capitol.
I think that is a different storyline versus had MOST gone to the Capitol. It's not really all that critical but it's worth noting. MOST of them did not heed the call to go. Some did, apparently single digit percentages.
As noted above, Trump might not have passed the legal threshold for incitement, but his actions make him responsible for it, in my view.
He and his folks were citing all sorts of nonsense about the voting. That got people riled up, some more than others.
