The 2024 Democratic National Convention starts tomorrow. Here's what to know.

Washington — Vice President Kamala Harris is riding a wave of voter enthusiasm into the Democratic National Convention that has transformed the race against former President Donald Trump three months before the election. 

The four-day convention in Chicago begins Monday, about a month after President Biden ended his reelection campaign as a growing number of Democrats questioned the octogenarian's ability to handle the duties of commander in chief for another four years. 

Democrats quickly united behind Harris, who named Minnesota Gov. Tim Walz as her running mate.
