Colorado Rep. Jared Polis has a lot of fundraising clout for a guy with a mere seven months of House service.

The Jared Polis Victory Fund, a joint fundraising committee the wealthy freshman congressman organized in May, donated $139,500 in late June to 31 Democratic campaign committees, according to a filing Friday with the Federal Election Commission.

The largest chunk of funds, $30,000, went to the Democratic Congressional Campaign Committee, the campaign arm of House Democrats that will be defending the party’s 256-178 majority in the 2010 elections.
