I suspect many of the young people on the left, who have been coddled by their parents since the day they were born and told how special they were, will not take kindly to anyone telling them what to do and taking away their internet for even a few days.
If I were the powers that be, I would not make a move, until I got the gun ban in place. They can not afford any kind of resistance with so many guns in the hands of the citizens. Now after the wars we have fought in the middle east, we have a strong cadre of citizens who are familiar with urban warfare, and have a strong political leaning toward conservatism.
Some have suggested that at that point they would invite the UN to help keep the peace. That would be the event that would drive those sitting on the fence into joining the resistance. The Left and the Right would join forces to fight the invasion of the blue hats.
