A few days after Ohio’s Democratic U.S. senator announced he raised a historic amount of money in the last three months, the Republican who wants a rematch to unseat him next year has released his fundraising figures.

Brown and Mandel rack up the money for their Senate race rematch

Republican state Treasurer Josh Mandel says he raised nearly $1.5 million in the first three months of this year. That includes donations to Mandel’s campaign and to a joint fundraising committee that supports him.

Last week, the incumbent Democrat, Sherrod Brown, announced his campaign had raised $2.4 million – a record for him during a single quarter of a non-election year. And right now, Brown has nearly $5 million in his campaign account, which is twice the cash reported on hand by Mandel.

Both candidates are likely going to need the money. The 2012 Brown-Mandel contest was the most expensive U.S. Senate race in Ohio history. And Mandel may have to also run in a primary.
