Concord — Democrat Colin Van Ostern and Republican Ted Gatsas are leading the cash race in the contest for governor, out raising their closest rivals by nearly half a million dollars.

Campaign finance reports filed on Wednesday reveal for the first time the financial strength of all seven major candidates. The reports offer a glimpse into where the funding for each candidate comes from, how the campaigns are spending their money, and what they have left to spend before the Sept. 13 primary.

The financial positions of the candidates vary widely. Three candidates — Gatsas, Democrat Mark Connolly and Republican Frank Edelblut — are heavily contributing personal funds to their campaigns. Democratic candidate Steve Marchand, meanwhile, shows plans to spend more money than he currently has on hand.

Van Ostern, an executive councilor, leads the Democratic candidates with $1.01 million raised. He has spent $607,000 — more than his closest competitor has raised. Former state securities regulator Mark Connolly, by contrast, records recipients of $556,000, but roughly $100,000 of that is a personal loan.

Marchand, in comparison, raised about $102,000 and spent $81,000. He is recording plans to spend at least $26,000 more through the primary.

Gatsas, the mayor of Manchester, also recorded bringing in just over $1 million, but at least $75,000 comes from a personal loan. On the Republican side, Edelblut has the most cash on hand, after loaning himself $750,000. He raised just $80,000 from others.

Executive Councilor Chris Sununu, meanwhile, has raised $588,000. Sununu jumped in the race in late 2015, giving himself a significant fundraising jump on most of his Republican competitors, yet his fundraising falls far short of Gatsas’. State Sen. Jeanie Forrester brought in $237,000.
