A recent New York Times and Sienna College poll found that in six key swing states 71% of black voters would back Mr Biden in 2024, a steep drop from the 92% nationally that helped him win the White House at the last election.

I never heard that so many black people supported (and still support) Trump.

Somewhere else I see this sentence, which sounds a lot more plausible to me:

There’s little evidence that Trump is making significant inroads with Black voters, who polls show remain overwhelmingly supportive of President Joe Biden.

Can someone unconfuse me please?
