U.S. Vice President Kamala Harris formally accepted the Democratic presidential nomination on Thursday, in a historic step that kicks off a three-month dash to Election Day.
Her challenge now is to harness the energy and excitement of a party reinvigorated by her rapid ascent. It amounts to an existential test for Harris, who remains undefined in the minds of many voters and has less than three months to build — and hold — a winning electoral coalition.
"On behalf of everyone whose story could only be written on the greatest nation on Earth, I accept your nomination to be president of the United States of America,” Harris said.
