If violence is acceptable in politics, where isn't it acceptable?

I'm not too concerned that Gianforte got elected given that two-thirds of the ballots were cast before the assault happened. What I want to know is, how many of those who voted for him early would change their vote now that they know about his violent attack? Knowing that will tell us something about the health of our democracy.
Given that Dear Leader in the Oval Office, I suspect the patient is very sick.
