Democrats have less than 3 weeks to select nominee following Biden drop-out

Among those predicted to compete with Harris for their place at the top of the Democratic ticket are California Governor Gavin Newsom, Pennsylvania Governor Josh Shapiro, and Gretchen Whitmer, though all three have since endorsed her. Whether any serious challengers emerge remains to be seen.

According to the Associated Press, while the convention doesn't begin until August 19, Ohio mandates that candidates be on the ballot by August 7. The state's legislature recently axed that requirement, though the change doesn't come into effect until September 1. Should the party fail to nominate someone by August 7, it could face legal challenges in the state. A virtual roll call is expected to be held prior to the convention, though no date has been set yet.

In a statement to CBS News, Democratic National Committee Chairman Jaime Harrison explained that, "in the coming days, the Party will undertake a transparent and orderly process to move forward as a united Democratic Party with a candidate who can defeat Donald Trump in November. " He said the process "will be governed by established rules and procedures of the Party, and that delegates are "prepared to take seriously their responsibility in swiftly delivering a candidate to the American people."

DNC executive committee member Alan Clendenin said he believed a "supermajority" of delegates would support Harris for the nomination, noting that at the end of the day, "the delegates at the convention are the ones who place our candidate on the ballot."
