Biden is the first sitting president to drop out of running for reelection since Lyndon B. Johnson in 1968 — leaving the race against Donald Trump in turmoil.
"While it has been my intention to seek reelection, I believe it is in the best interest of my party and the country for me to stand down and to focus solely on fulfilling my duties as president for my term," Mr. Biden posted in a statement on social media.
I doubt the nomination is really "open". The only way they get to spend their war chest is if VP Harris runs (and she is). I can't see the DNC nominating anyone else with such little time left.
