I think its because Trump has done nothing but forement violence and hate for 8 years. That builds up real hate from the opposing side. Plus his party breeds these little white school shooters and serial killers so it was ironic that Trump almost got killed by one of his own.The same nikkas in here clutching their pearls were wishing trump got slumped.
Its interesting watching sheep behavior
Harris, Walz hasn't done any of that. So there isn't going to be the same reaction. If anything the worry is the violence Trump will continue to be the avatar for if he loses again.
Its one thing for Trump to lose once. Losing twice will put white people over the deepend. Especially because they will believe it was stolen from Trump twice.
