Kamala Harris is leading Donald Trump in multiple national polls ahead of the Democratic National Convention, with notable gains among younger and older voters. Emerson College polls show Harris ahead by 4 points, a 10-point swing since July, and other polls confirm her lead across diverse demographics, including women and independents. Betting markets also favor Harris, with her odds improving dramatically since Joe Biden dropped out of the race. Meanwhile, Harris' campaign visit to Raleigh focuses on economic policies and preventing price gouging. Despite her lead, Harris' campaign faced scrutiny for running ads that mimic news articles, which Google has not deemed misleading.
