Controversy

Shortly after the final results for the Republican primary, controversy almost immediately emerged about Scott Walker’s victory, as Lee Murphy had been seen by many as the favorite to win. Murphy refused to concede and took to Facebook, saying, “Friends, thanks for all your support- something stinks here and I will not be conceding anytime soon. Need to investigate big time. A Dem wins a Republican primary?”^[4] Murphy also called for an investigation into the results.^[7] Walker responded by saying that God had led his campaign to victory.^[8] Student and community activist Andrew Webb declared his Republican write-in candidacy on September 17, 2018, hoping to gain support from dissatisfied Republicans.
