Donald Trump’s Monday swearing-in marks just the second time in US history that a president lost the office and managed to return to power — a comeback cementing his place within the Republican Party as an enduring, transformational figure rather than a one-term aberration.

Trump won his second term by building a new coalition that includes White working-class voters, Blacks and Hispanics, and young men of all races and ethnicities. He expanded the once-staid GOP into a more diverse group driven by economic populism and a strong distrust of institutions.
