Democrat Cal Cunningham raised more than $28 million in the third quarter of the year for his campaign to unseat Sen. Thom Tillis (R-N.C.), setting a record for the most raised in a single quarter by any North Carolina politician.

Cunningham’s $28.3 million quarterly haul is nearly four times as much as the $7.4 million he raised in the second quarter. The massive fundraising sum likely puts Cunningham in a strong position heading into the crucial final month of his campaign.

His campaign said that more than 40,000 North Carolinians had given to his Senate bid over the past three months, with many of them contributing more than once. Ninety-six percent of donations were under $100, the campaign said.
