It seems like the rioting in Portland suddenly stopped. Why? In May, an Antifa candidate for Portland Mayor came in second against Ted Wheeler, triggering a run off election. She was trailing him 49 to 24 percent.
Until the first week of September, when Wheeler began polling with a 63 percent negative rating after 100 days of riots. This virtually guarantees that Antifa will have their candidate elected and will own the city of Portland.
So in short, the riots in Portland have stopped because the battlefield has moved on.
