UPDATE: GOP race for governor too close to call

Candidates Matt Bevin, James Comer, Hal Heiner and Will T. Scott waged a furious campaign in an unusually crowded field for a Republican primary in a state that has long been dominated by Democrats.

Heiner conceded on Tuesday night, congratulating Bevin, and Scott lagged far behind the other three.

But Comer and Bevin were locked in a virtual tie with nearly all precincts reporting.

The campaign was overshadowed by allegations from a former girlfriend that Comer had emotionally and physically abused her while the two dated in college more than two decades ago.
