Herschel Walker, a former star running back whose actual political stances are ill-defined to nonexistent, has secured the primary nomination for Republican senator in Georgia, according to multiple outlets. Walker is a divisive figure, even among conservatives. While former President Donald Trump and Senator Lindsey Graham (R-S.C.) encouraged him to run for office, Senate Minority Leader Mitch McConnell was once so concerned with Walker’s candidacy that he suggested that ousted Republican Sens.
