You see it in the maps. In 2015, 1.4 million Hong Kongers voted in elections in which pro-Beijing candidates swept the city's 18 district councils. Last week 2.9 million Hong Kongers voted and pro-democracy candidates won every district but one. That is an increase in turnout of more than 100 percent and a stunning rebuke both of Beijing and of chief executive Carrie Lam, who has failed to respond adequately to the demands of the pro-democracy movement that has disrupted Hong Kong for the past six months. Maps of the city once shaded pro-mainland blue are now pro-liberty yellow.
