US Representative Mike Collins, a Trump-endorsed congressman and self-described "MAGA warrior," has won the Georgia Republican primary runoff, defeating former college football coach Derek Dooley to secure the party's Senate nomination. Collins, a trucking executive and anti-abortion hardliner who has denied the legitimacy of the 2020 election, will now challenge incumbent Democratic Senator Jon Ossoff — one of the most competitive Senate seats heading into the November midterms. Ossoff immediately responded by labelling Collins "a notorious bigot, antisemite, and extremist currently under federal investigation for the illegal misuse of tax dollars," setting the tone for what is expected to be a fiercely contested race in a state Republicans have not won a Senate election in since 2016.
