 A person familiar with the matter says Harris spent much of Sunday surrounded by family and staff and made more than 100 calls to Democratic officials to line up their support. Reaching out to Democratic Party delegations from Florida to New Hampshire to the Carolinas, the Associated Press found many have already lined up behind Harris, while others plan to hold conference calls today. If Harris does lock up the nomination, she must also pick a running mate and boost her candidacy with just two and a half months between the end of the Democratic convention in Chicago and Election Day.
