CLEVELAND, Ohio — Democratic Sen. Sherrod Brown has about $1.8 million left over from his successful re-election campaign, according to a new elections filing.

In a Thursday filing with the Federal Elections Commission, Brown’s campaign reported spending about $4.8 million and raising about $731,600 during the most recent filing period, from Oct. 18 to Dec. 7.

His Republican opponent, Rep. Jim Renacci, in his own filing reported raising about $212,600 and spending about $700,300 during the same time.

Including the new numbers, Brown raised about $28.7 million total through the course of his successful re-election campaign, while spending $27.4 million.

In contrast, Renacci’s campaign reported raising a total of $2.6 million, receiving $1.4 million from an affiliated committee, and spending $4.8 million.

That means Brown out-raised and outspent Renacci roughly six-to-one.

All told, that leaves Brown with $1.8 million left over as he considers whether to seek the Democratic nomination for the presidency in 2020. His victory in Ohio in a year Republicans won the governor and other key statewide offices has been part of his pitch to national Democrats. But on any path to the White House, he can’t expect to replicate the lopsided fundraising advantage he enjoyed this year.

Also of note, on Nov. 11, Renacci repaid himself about $3.5 million of the roughly $4 million he had loaned his campaign earlier in the year, leaving his campaign with a cash balance of about $4,200.

Renacci, who became wealthy in business before entering politics, loaned himself the $4 million in April, before he won the May Republican Senate primary, to try to attract additional donors. Privately, Ohio Republicans became increasingly frustrated through the course of his campaign as it appeared that Renacci was holding back a large portion of the money to eventually repay himself.

MeToo Ohio, a Republican PAC that formed to attack Brown over details from his nasty 1986 divorce, also filed a campaign finance report on Thursday. Including its final donations, the group spent $618,200 attacking Brown, mostly via TV and Internet ads. The group also paid $10,000 in consulting fees to Christina Hagan, a Republican state representative from Stark County who served as its executive director. MeToo Ohio was the largest outside group to spend money in Ohio’s Senate race this year, a far cry from the tens of millions of dollars in third-party ads Ohioans have seen in previous races.

MeToo Ohio raised $645,000, nearly all of which came from a pro-Renacci Super PAC or “dark money” groups designed to make its donors untraceable. Only one donation, $25,000 from Akron’s Anthony J. Alexander on Oct. 19, came from an identifiable individual donor.
