Stabenow had her best fundraising quarter ever, getting $1.54 million in donations. She spent $420,000 and had nearly $7 million on hand.
Hoekstra wouldn't address if the ad had affected his donations, instead saying his campaign had "just about outperformed every expectation" in how much he could raise for a Senate run.
Durant, a Detroit charter schools executive opposing Hoekstra in the GOP primary, reported raising $581,000 and spending $257,000, leaving $1.51 million on hand — nearly as much as Hoekstra. Republican Randy Hekman reported he raised $142,000, spent $135,000 and had about $7,000 on hand.
Reports for other GOP candidates weren't available on the Federal Elections Commission's website.
