We know running for office means bringing in, and spending, a lot of money. But how much, exactly?

We're more than 15 months from the 2016 elections, when all eight of Minnesota's Representatives in the U.S. House will be up for re-election or vacating their seat.

Already, documents filed with the Federal Election Commission show some of them have brought in hundreds of thousands of dollars just through the most recent quarter (from April 1 through June 30).

MPR News says the filing deadline for this period was Wednesday.

Below you'll see how much in contributions (money from others) they've acquired both this period and for the election cycle. Also noted is their cash on hand as of June 30, which includes contributions from individuals, donations through PACs, and loans from the candidate's own bank account or a third party.
