US President Joe Biden drops re-election bidUS President Joe Biden ended his reelection campaign on Sunday after fellow Democrats lost faith in his mental acuity and ability to beat Donald Trump, but did not immediately endorse Vice President Kamal Harris to replace him as candidate. Biden, 81, in a post on X, said he will remain in his role as president and commander-in-chief until his term ends in January 2025 and will address the nation this week. “It has been the greatest honor of my life to serve as your President. More than one in 10 congressional Democrats had called publicly for him to quit the race. Biden’s historic move – the first sitting president to give up his party’s nomination for re-election since President Lyndon Johnson in March 1968 – leaves his replacement with less than four months to wage a campaign.
