Senate Majority Leader Chuck Schumer and former President Barack Obama have separately expressed concerns about President Joe Biden's re-election bid due to poor polling data and doubts about his ability to defeat Donald Trump. Discussions have surfaced about urging Biden to reconsider his candidacy, with calls from various Democratic leaders like Nancy Pelosi and Adam Schiff. Despite Biden's insistence on staying in the race and receiving some support from key Congressional caucuses, there is growing pressure within the party for a reassessment. Biden has retreated to Delaware for contemplation as tensions rise within the Democratic Party over his campaign's viability.
