ATLANTA (AP)— With a little more than 50 percent of Georgia’s disctrics fully reporting in, the Associated Press is calling the Republican runoff for Secretary of State Brian Kemp.

Kemp has won a bruising Republican runoff in the race for Georgia governor, leveraging a secret recording of his opponent and a late Trump-Pence endorsement.

As of posting, Kemp had 68.95 percent of the Georgia vote, compared to Lt. Gov. Casey Cagle’s 31.05 percent.

With Tuesday’s win against Lt. Gov. Casey Cagle, Kemp faces Democrat Stacey Abrams. She could become the country’s first black woman governor.

The race will test Democrats’ assertion that changing demographics have turned the Republican stronghold into a swing state.

Cagle’s campaign was rocked by a secret recording in which he says he helped pass a “bad public-policy” bill for political gain.

Gov. Nathan Deal and the National Rifle Association supported Cagle. But Kemp was boosted by the president’s endorsement.
