Jon Lieber, Eurasia Group's head of research and managing director for the firm's coverage of United States political and policy developments, shares his perspective on US politics from Washington, DC.

President Trump has made his VP selection, JD Vance, Senator from Ohio, a 39-year-old who rose to prominence as the author of a book explaining the troubles of the white working class who voted for Trump in 2016, to a much broader population of Americans who were at the time, struggling to understand how Trump pulled off his surprising victory. Vance then reinvented himself as an investor and then a prominent Trump critic, warning about Trump's dangers to America, and saying that he is America's Hitler. And then went on to reinvent himself yet again as a populist champion of the working class, running for Senate in the seat he ended up winning.
