Warnock (D-Ga.) and Republican challenger Herschel Walker, the previous soccer star, face off in probably the most anticipated debates in the midterm elections — a race that might tip the stability of get together management in the U.S. Senate. The night encounter in Savannah, Ga., is the newest in a string of debates in marquee Senate races, together with one Thursday night time in Wisconsin that shortly turned private between Sen. Ron Johnson (R-Wis.) and Democratic challenger Mandela Barnes.
