Billionaire Rick Jackson defeated Georgia Lt. Gov. Burt Jones in Tuesday’s Republican gubernatorial runoff, after the race was called with Jackson holding 53% of the vote to Jones’ 47%. The runoff followed a May primary in which no candidate won a majority, with Jones taking 38% and Jackson 34%. Jones had been endorsed by President Donald Trump, and also received a late endorsement from Republican Gov. Brian Kemp over the weekend. After the result, Trump congratulated Jackson and said he had campaigned on being “TRUMP,” while also offering supportive comments about Jones. The report said Jackson spent more than $100 million on the race and will face Democratic nominee and former Atlanta Mayor Keisha Lance Bottoms in the general election.
