It’s not uncommon for organizations to give campaign funds to both political parties so that they nurture alliances on both sides of the aisle.

But it is pretty rare to see an individual donor give large amounts to both Democratic and Republican organizations.

Jon Huntsman Sr., a businessman who is the namesake father of the Republican governor of Utah, last month gave the maximum $30,400 to the National Republican Senatorial Committee (NRSC) and the Democratic Senatorial Campaign Committee (DSCC), according to a review of recently filed campaign finance documents. His wife Karen also gave the maximum amount to both Senate campaign committees, which are partisan rivals in the 36 Senate contests that are on 2010 ballots.
