Surge in Democratic enthusiasm raises hopes of winning swing states

Exclusive: Memos show massive jump in contributions and volunteers for Kamala Harris campaign, in addition to $200m haul

The launch of Kamala Harris's campaign has injected newfound energy into her party with less than 100 days to go in the election cycle and raised Democrats' hopes of winning battleground states that once seemed irretrievably lost to Donald Trump, according to a set of memos exclusively shared with the Guardian.

The memos show that Democratic parties in battleground states saw a dramatic surge in contributions and volunteer sign-ups in the past week, in addition to the Harris campaign's record-breaking fundraising haul of $200m.
