America's first Black president, Obama has thrown his considerable political capital behind Harris as she seeks to make history herself on Nov. 5 as the first woman and first Black and South Asian person to be elected U.S. president. Obama was introduced by his wife, Michelle, who tops Democrats' wish list as a future president. "America, hope is making a comeback," Michelle Obama said, in a nod to Obama's first presidential campaign in 2008. At 63, Barack Obama loomed large in the messy deliberations that led Biden to step out of the race last month and endorse Harris, his vice president. Democrats see abortion rights as a winning issue in this campaign and Harris had led the charge as vice president.
