President Joe Biden is leading among young Americans in a hypothetical rematch of the 2020 presidential election, with 52% support among 18-29 year olds. He also has a slim lead nationally, with 40% support overall. A new Messenger/Harris poll puts Donald Trump ahead of Biden in a four-way match-up by eight points, with 41% support. However, most voters do not want either candidate to run for the presidency again. In a weekly national voter poll, Biden has a 43% to 42% lead over Trump, marking a gain for Biden and a loss for Trump, with 84% of Democrats backing Biden and 86% of Republicans backing Trump.
