50% of the electorate wouldn't be hurt by sanctions, or 50% of the electorate would be arrested?
In either case, I'm referring to the president, his staff and cabinet. People actually directly making decisions who won't see any consequences from sanctions.
Why do you think violence would accelerate things? They don't need the violence to be real to react to it, so if it would accelerate things for them they would just do it. Likewise, protest or strikes aren't going to magically be treated as peaceful. They'll just call it an insurrection regardless. . It's why a lot of people hesitate to act. There's a big difference between a protest where your local police department might use tear gas if you stick around after they tell you to leave and a protest where the president is encouraging random nut jobs to hit you with a car, has encouraged your police department to shoot you, and is sending the national guard to shoot you.
