He said the idea of usurping the nomination from Biden and then winning is "certifiably insane." AdvertisementThe chairman of the Democratic National Committee said the idea of replacing President Joe Biden as the party's candidate and winning the election in November is "certifiably crazy actually." Nevertheless, Super Tuesday, where roughly a third of the nation's Democratic delegates will be doled out, is fast approaching. That hasn't happened, though, since Democratic President Lyndon B. Johnson said he wouldn't run for reelection in 1968 after winning the New Hampshire primary in late March of that year. The 1968 contested convention was chaotic — even dangerous at times — and the Democratic candidate chosen, Vice President Hubert Humphrey, lost in November by 110 electoral votes.
