I wouldn't entirely discount them. January 6th showed that Trump could rile up enough support to literally get a crowd of a few thousand to enter into open treason on his behalf. If anything, I wouldn't be surprised that the convictions stemming from it thus far have further radicalized some of those who held back into believing they're legitimately at risk of persecution, leaving them more likely to take such extreme actions in the future. While I don't think Trump himself could pull it off, I wouldn't be at all surprised if more competent individuals on the far right took note of this and will do their best to channel the passion and loyalty Trump inspires in his supporters towards much more effective and dangerous action if he gets another shot.
