Canova raised $557,000, powered by small donations. Nearly 15,300 people donated, for an average contribution of $20. Only six donors gave the maximum amount allowed under law, meaning he still has a significant pool of people to tap into for future donations.

In the four days following Obama’s endorsement, Canova received nearly $100,000, according to his campaign — almost a quarter of what he raised in the three-month period, even though they never actually fundraised off the endorsement.
