Following President Joe Biden's withdrawal from the 2024 presidential race, enthusiasm for Vice President Kamala Harris's candidacy has surged within the Democratic Party. In just days, hundreds of volunteers have registered across various states, with notable increases in Michigan, Nevada, and New Hampshire, indicating a rejuvenated grassroots movement. Democratic lawmakers report unprecedented donation levels, with some congressional campaign committees achieving record-setting fundraising days. This shift in momentum has revitalized the party's hopes of regaining control in the House and holding onto the Senate against Republican challenger Donald Trump. Despite skepticism from some Republicans who recall past electoral failures, Democrats assert that Harris's leadership provides a clearer contrast in the upcoming election. As the campaign accelerates, local Democratic organizations are mobilizing volunteers at levels not seen since Barack Obama's campaign in 2008.
