 AP News. I'm Ed Donovan. President Biden has been saying average Americans still want him to stay in the race after his debate performance with Donald Trump. But a new AP Newark Center poll shows only about three in 10 Democrats are extremely or very confident the president has the mental capability to serve. The AP's Amelia Thompson DeVoe has more. All of this has left Americans overall much more likely to think that Trump can win the 2024 election than Biden.
