Vice President Kamala Harris’ presidential campaign said it raked in a whopping $310 million in its July fundraising efforts – more than double the amount raised by her Republican rival last month – and has $377 million cash on hand, marking the latest sign of how transformative and energizing the change to the top of the Democratic ticket has been among grassroots and high-dollar supporters.

A majority of that $310 million haul, more than $200 million, was raised in the first week of Harris’ candidacy, the campaign said in a statement, with two-thirds of the fundraising coming from first-time donors to the campaign.
