Several Democratic figures, including Sen. Sherrod Brown, Sen. Jon Tester, Sen. Martin Heinrich, and others, have expressed concerns about President Joe Biden's ability to lead the party in the upcoming election due to issues such as health and performance. Calls for Biden to step aside have increased, with discussions about potential replacements like Vice President Kamala Harris. Some party members, like 'The Young Turks' host Ana Kasparian, have distanced themselves from Biden, citing concerns over his candidacy and power struggles within the Democratic Party. Figures like former Sen. Doug Jones and Gov. Phil Scott have also questioned Biden's competency and indicated they may not support him if he remains on the Democratic ticket.
