Early votes are early warning for campaigns; 8 million already cast

McClatchy reports:

A week before Election Day, more than 8 million people in some 30 states have already voted, a sort of early warning sign to the major parties of states where they’re doing well and where they’re already falling behind.

Besides convenience to voters, early voting provides almost real-time – but somewhat incomplete – snapshots of how some campaigns are faring.
