Wall Street Journal: “Many Democratic and Republican primary races have devolved into bruising political knife fights.”“New district lines in states like California have pitted once friendly House incumbents against each other, while other candidates attempting to make political comebacks are willing to use their sharp elbows against their successors to get ahead. Some races in both parties have centered on who is the most or least MAGA, showing the central role of President Trump in the elections.”“While political races have always had a certain degree of ugliness, some campaigns this year have also embraced artificial intelligence to create fake images of their opponents and give a new look to negative ads.”
