Vice President Kamala Harris appears to have energized Democrats in the early days of her candidacy, with the surge in warm feelings extending across multiple groups, including some key Democratic constituencies that had been tepid about President Joe Biden. That's according to a new poll. About 8 in 10 Democrats say they would be very or somewhat satisfied if Harris became the Democratic nominee for president. The survey from the AP-NORC Center for Public Affairs Research was conducted after Biden withdrew from the race. The rapidly changing views among Democrats in such a short time span underscore how swiftly the party has coalesced behind Harris as its standard-bearer.
