Harris picks up surge of volunteers in Florida

More than 7,000 Floridians have signed on to help with Vice President Kamala Harris' presidential campaign — its largest surge of volunteers so far.

Why it matters: The numbers, shared with Axios by the Harris campaign, show "an overwhelming groundswell of support" in the Sunshine State, Florida director Jasmine Burney-Clark said in a statement.

• And it potentially signals untapped enthusiasm among Democrats in Florida as the state's voter rolls and election results have grown increasingly red in recent years.

By the numbers: As of Wednesday, the campaign had amassed more than 6,600 volunteers in Florida, a number that swelled to more than 7,200 by Thursday, per the Harris campaign.

• The campaign had recruited by Wednesday about 5,700 volunteers in Pennsylvania, 4,300 in Georgia and 3,300 in Michigan — the three most populous states most likely to decide the November election .

Reality check: Republicans have continued to dominate voter registration in Florida with a lead of more than 950,000 voters as of June 30.
