Unlike in 2016, when a large group of voters who disliked both Trump and Hillary Clinton broke sharply for Trump, the opposite is happening now, according to public polling and private surveys conducted by Republicans and Democrats alike.

It’s a significant and often underappreciated group of voters. Of the nearly 20 percent of voters who disliked both Clinton and Trump in 2016, Trump outperformed Clinton by about 17 percentage points, according to exit polls.

Four years later, that same group — including a mix of Bernie Sanders supporters, other Democrats, disaffected Republicans and independents — strongly prefers Biden, the polling shows. The former vice president leads Trump by more than 40 percentage points among that group, which accounts for nearly a quarter of registered voters, according to a Monmouth University poll last week.

“It’s a huge difference,” said Patrick Murray, who oversees the Monmouth poll. “That’s a group that if you don’t like either one of them, you will vote against the status quo. And in the 2016 election, Hillary Clinton represented more of the status quo than Trump did. In this current election, the status quo is Donald Trump.”
