Even without counting outside spending, Ohio's U.S. Senate race is officially the most expensive in state history.
Incumbent Sen. Sherrod Brown (D) and GOP challenger Josh Mandel have raised $25 million this cycle, according to the Dayton Daily News.
Brown has raised $15.3 million to date, compared to Mandel's $9.9 million. He also has about $6.5 million on hand, compared to Mandel's $4.9 million.
But outside spending in the race favors Mandel, the state treasurer. Groups have poured an estimated $13 million into the race, with conservative groups like the U.S. Chamber of Commerce and Crossroads GPS spending about $10.5 million on behalf of Mandel. Progressive groups have contributed only $2.5 million on behalf of Brown, who faces more spending by the opposition than any other senator or Senate candidate in the country.
The next most expensive campaign was the 2006 race between Brown and Mike DeWine, now the state attorney general. That entire race cost $23 million, according to the Daily News.
A HuffPost Pollster analysis of the race shows Brown leading Mandel, 45.9 to 39.3.
