“One of the juiciest targets on the Senate map in 2020 is Republican David Perdue, who is running for his second – and he says final – term in the U.S. Senate. The businessman has become one of President Donald Trump’s most prominent D.C. allies – even in his most isolating moments – and he plans to stick to the outsider, anti-establishment message that won him his seat in 2014. No well-known Republicans are expected to oppose Perdue in a primary, but several Democrats have hinted they’re interested in challenging the multi-millionaire in 2020. Most are waiting for Stacey Abrams to decide her next step after her near-miss in the race for governor. If she sidesteps a 2020 race, Democrats could be in for a tempestuous primary fight from potential candidates that include outgoing Columbus Mayor Teresa Tomlinson, Pastor Raphael Warnock, former congressional candidate Jon Ossoff and ex-Senate candidate Michelle Nunn”.
