Polls show Trump leading Biden by 6%.
According to a New York Times and Siena College poll, Trump has a 6-point lead over Biden among potential voters, which will put even more pressure on Biden.
It is reported that the New York Times/Siena College poll is one of the most closely watched polls in American politics.
The poll released on Wednesday put Mr. Trump at 49 percent and Mr. Biden at 43 percent, and suggested that concerns about Mr. Biden's age were the main reason for the turnaround. Nearly three-quarters of voters, or about 74 percent, said Mr. Biden was too old, up 5 percentage points from last week's poll.
