Ex-Rep. Rob Portman (R) will report raising $2.35M in the first fundraising quarter, his best quarter to date.

He begins the 2nd quarter with $7.6M on hand and more than 13K individual donors.

Campaign spokeswoman Jessica Towhey said 80% of the donations have come from inside the Buckeye State.

Portman, who doesn’t have a primary now that auto dealer Tom Ganley abandoned his bid in favor of a race against Rep. Betty Sutton (D), likely will have a lower burn rate than his two Dem challengers. He spent $735K in Q1.
