President Biden's campaign is planning a first-of-its-kind fundraiser featuring himself along with former Presidents Bill Clinton and Barack Obama. The event would take place in March or April and aim to raise significant funds while also energizing the Democratic base. It underscores the view among Biden's allies that Democrats need a united front to help him win reelection against expected opponent Donald Trump. Biden's campaign is ramping up efforts earlier than expected, including aggressive travel, ads, and outreach to key voting blocs.
