Democratic Sen. Raphael Warnock and Republican challenger Herschel Walker met Friday for their first and only debate in a brutally competitive Georgia Senate race, clashing over abortion and inflation, but agreeing that the 2020 election was legitimately won by President Joe Biden. The debate was marked by frequent interruptions by Walker, a first-time political candidate, who sought to portray the Democratic incumbent as a creature of Washington who votes with Biden too often. Warnock defended his votes on a sweeping climate and health care bill and gun violence prevention legislation during his two years in the Senate. At the center of the recent controversy stands Walker, the former University of Georgia football star whose once-shining brand in the state have take a hit amid a drumbeat of tabloid-style stories and attack ads detailing past domestic abuse allegations against him from an ex wife and a recent claim that the Republican paid for a woman’s abortion, which he denies.
