Optimism for the future of the United States took a dive amid rising concern over the delta variant and the Biden administration’s management of the virus, a new poll found.

Roughly 55% of those surveyed in the ABC News/Ipsos poll said they are pessimistic about the future of the country; a spike from 36% from a May 2 poll. People in the U.S. were 28 percentage points higher in optimism than pessimism in the May poll.
