The evolution of Kamala Harris' stances on single-payer health care, fracking and the Supreme Court

When then-Sen. Kamala Harris was running for the 2020 Democratic nomination for president with one of the most liberal voting records in the Senate, hers was a long-shot candidacy.

But now, less than five years later, as the Democratic presidential nominee, Harris is moderating some of her more controversial policy positions. 

With barely 80 days to go until Election Day, Harris is likely to need independent voters to prevail in a competitive race against former President Donald Trump in the general election this fall. She's spent 3.5 years in the executive branch examining and reconsidering some of her policy stances, and there have been some shifts.
