From @ShaneGoldmacher at the NYT:

The DeSantis campaign said it had around 40,000 donors in May as “we raised over” $8.2 million, according to text messages and emails to supporters asking for more donations. That works out to an average of more than $200 per donor — a figure far higher than is typical for a campaign heavily funded by grass-roots support. By comparison, Senator Bernie Sanders, who was a Democratic online fund-raising powerhouse, raised $5.9 million in his first 24 hours in 2019 — but from 223,000 donors, for an average donation of around $26….

How a campaign raises money matters. Because of strict campaign contribution limits of $3,300 per person for the primary, campaigns that raise money chiefly from bigger contributors cannot return to those same donors again and again for support.

Small contributors are particularly valuable because they can give $30 more than 100 times before bumping up against contribution caps.
