As you pointed out, if Trump wins, there will be violence on a massive scale, all instigated by leftwing activists. However, I think the murder and mayhem will be far greater than what many of us are expecting.
Indeed, however it wouldn’t be surprising if the violence started weeks before the election to scare off tepid voters who would vote for Trump over Xiden as the leftists/GOPe/deep state/uniparty would want them to stay home.
