My guess is never, but let's see what happens in November. Cancelling the elections or obvious tampering or outright disregard of the outcome will probably spark mass protests. Things can happen from that. There will be heavy military presence, but if millions show up... who knows? Still, we tough and independent Americans will likely just bend over and take it in the ass. It looks like the home of the brave was the easiest country for the wealthy elite to take.
