evidence: As President Joe Biden today bowed to the growing chorus of elected Democrats and Democratic voters calling for him to exit the 2024 race, everyone is taking another good hard look at Kamala Harris. "Today I want to offer my full support and endorsement for Kamala Harris to be the nominee of our party this year, " Biden wrote in a social media post, calling his selection of Harris to be his vice president "the best decision I’ve made." [...] But as Harris emerged as the favored substitute for Biden, more voters seem to be warming to her. A Washington Post poll found that the vast majority of Democratic voters nationwide would be "satisfied" with Harris at the top of the ticket. The same poll found her narrowly beating Trump in a head-to-head election among registered voters.
