New York Times: “A sizable portion of the American population has been convulsing with outrage at President Trump for more than a year. Millions of people who previously took only mild interest in politics have participated in protests, fumed as they stayed riveted to news out of Washington and filled social media accounts once devoted to family updates and funny videos with furious political commentary.”

“Yet public life on the whole has remained surprisingly calm. A significant factor in keeping the peace has surely been anticipatory catharsis: The widespread expectations of a big Democratic wave in the coming midterm elections are containing and channeling that indignation, helping to maintain order.”

“What will happen if no such wave materializes and that pressure-relief valve jams shut?”
