When asked if Americans are doing better than they were four years ago, Vice President Harris emphasized that she is the only candidate on the stage who grew up in a middle-class family. She promoted her “opportunity economy,” drawing attention to a plan she outlined to help stabilize the housing market and support small businesses. Mr. Trump denied that he was involved in Project 2025, which is a plan to reform the entire federal government if Mr. Trump is elected. Project 2025 was drafted by the Heritage Foundation and Mr. Trump’s allies. The plan includes more than 900 pages, aims to criminalize pornography, disband the Departments of Commerce and Education, remove abortion from health care, and limit efforts to force against climate change.
