As Kamala Harris prepares to accept the Democratic nomination for president, her speech at the Democratic National Convention is seen as a critical opportunity to define her image to the American public. Historically, post-convention polling bounces have been minimal, but in a closely contested race, even a small increase could be significant. Harris, less defined than her opponent Donald Trump, has the potential to sway undecided voters with her personal story and policy perspectives. Former President Barack Obama and former First Lady Michelle Obama have endorsed Harris, emphasizing her relatable background and commitment to the American people. However, Harris faces criticism for her campaign's lack of detailed policy proposals, a contrast to previous Democratic candidates. California Governor Gavin Newsom defended Harris, suggesting she will provide more detail in her convention speech.
