The case was reopened because of thousands of State Department emails turning up on a computer belonging to Anthony Wiener. These emails were found independently by the NYC FBI office. NYC FBI was evidently not briefed on the 'HQ' special treatment of Clinton and her minions.
Comey's promise to keep the Congress updated combined with the high certainty of a Cinton victory allowed for the second showcase 'investigation' and 'exoneration'.
