Four Charts That Explain Why Xi Could Be President for Life

China’s Communist Party has proposed ending the 10-year limit for the presidency, which would allow President Xi Jinping to serve as China’s leader indefinitely. The move alarmed many people outside China, who saw it as a further step back from democracy—although President Trump praised the move in a closed-door speech to Republican donors on March 3, adding, presumably as a joke, “Maybe we’ll have to give that a shot someday,” according to an article in the Washington Post.

These four charts explain why Xi can probably get away with ending the two-term limit (and why Trump probably can’t). I created them using data from the World Values Survey, which says it’s “a global network of social scientists studying changing values and their impact on social and political life.”
