Biden is likely to address those challenges and more in his State of the Union address on Thursday as he tries to convince Americans that he deserves another term. About one-third of Democrats said they’re not very or not at all confident in Biden’s mental capability in the new survey, up from 14 percent in January 2022. Only 40 percent of Democrats said they’re extremely or very confident in Biden’s mental abilities, with approximately 3 in 10 saying they’re “somewhat” confident. In the survey, 59 percent of Republicans are extremely or very confident that Trump has the mental abilities to be president. About 9 in 10 Republicans say Biden lacks the mental capability to serve as president, while a similar share of Democrats say that about Trump.
