Seventy-nine percent of Democrats said they would approve of Vice President Kamala Harris becoming the Democratic presidential nominee if President Joe Biden steps aside, according to a new Economist/YouGov poll.

Twenty-eight percent of Democrats think Harris would be more likely than Biden to win against former President Donald Trump in the fall, while 32% say Biden and Harris have about the same chances of winning. Less than a quarter say Biden would be more likely than Harris to defeat the former president.
