DENVER — Former Colorado Gov. John Hickenlooper’s Senate campaign reports a $5.2 million fundraising haul over the past three months, calling it a record for any Senate candidate in state history.

Hickenlooper’s haul is significant, though it comes as his fellow Democratic hopefuls have been shattering Senate fundraising records nationally. Hickenlooper in November will be facing Sen. Cory Gardner, who is considered the most vulnerable Republican senator up for reelection. Hickenlooper, a former presidential candidate, outraised Gardner in the first three months of the year.

The Democratic campaign on Wednesday reported raising the $5.2 million between April 1 and June 30. It said donations came from all of Colorado’s 58 counties.
