One thing has been missing from Kamala Harris' sudden rise as the Democratic choice for president against Donald Trump: contact with many reporters. She hasn't given an extended interview to a journalist since her change in status. Harris indicated that's about to change as Republicans have made it a campaign issue.

There are also many different ways that a candidate can reach potential voters that don't involve direct dealings with the press.
