Secretary of State Brian Kemp has had two roles this year: Running Georgia’s elections and running for governor of the state.

Democrats, including former President Jimmy Carter, have called on him to step aside, warning repeatedly of potential conflicts of interest.

Kemp is now facing renewed scrutiny after his office announced Sunday — without providing evidence and doing so just hours before Election Day — that it is investigating the Georgia Democratic Party for an alleged hack of the state’s voter registration system.

The move to publicly disclose the probe appeared to break with tradition in the office, which oversees voting integrity, as it differed from how Kemp’s team handled an earlier cyber breach at Kennesaw State University.

My earlier Slate commentary on this fiasco is here.
