The Democratic National Convention in Chicago is set to showcase Vice President Kamala Harris as the party's presidential nominee following President Biden's withdrawal from the race. Harris has energized the party, drawing large crowds and boosting fundraising efforts as polls show her neck-and-neck with Republican nominee Donald Trump. However, Democrats remain cautious, recalling the 2016 election and the challenges posed by Trump's enduring popularity. The ongoing conflict in Gaza has sparked internal tensions and could lead to protests during the convention, although polling indicates it ranks lower on voters' priority lists compared to economic issues. With 50,000 attendees expected, security is heightened around the venue as party members prepare to rally behind Harris, who is aiming to become the first female president. Despite the excitement, the party's unity and focus will be tested as they navigate both public sentiment and external controversies.
