After a pivotal debate, discussions among Democrats are intensifying about whether Vice President Kamala Harris would be a stronger candidate than President Biden. Despite Harris' support for Biden's campaign, Democratic insiders speculate that a significant drop in Biden's poll standings could trigger calls for him to withdraw. This sentiment is partly due to a CNN poll showing Trump leading Biden, with Harris performing slightly better against Trump. Discussions about Harris replacing Biden are ongoing, although she faces her own challenges with public perception and approval ratings.
