Vice President Kamala Harris has raised over $1 billion in her presidential campaign since July, significantly outpacing former President Donald Trump's fundraising efforts. This unprecedented figure was achieved through large fundraising events and a surge in online donations, though the exact total for September has not been disclosed. Despite this financial advantage, Harris' campaign remains concerned about effectively deploying resources in critical swing states. Both Harris and Trump are intensifying their campaign efforts, with Harris also leading slightly in national polls. Republican candidates continue to rely on substantial super PAC funding to close the financial gap, as the upcoming election is poised to be one of the most expensive in U.S. history, reflecting high donor enthusiasm on both sides.
