The Marlin Stutzman campaign has requested an advisory opinion regarding the Federal Election Commission regarding the treatment of campaign contributions when there is both a regular election and a special election on the same day.
Federal election law treats the elections as two separate events. However, that creates some questions when campaigns are trying to allocate campaign contributions to one campaign or the other. A donor merely want to support a candidate but the candidate's campaign needs to determine to which election the donor intended to contribute.
The Stutzman campaign asks whether this may come under the FEC arcane term of art "presumptive redesignation." We know that may sound as esoteric as "redactive voting" but it is a term used by the FEC to allow the redesignation of an amount in excess of a campaign limit to the "next election." This usually means that funds received in a given election year for a primary that are in excess of that cycle's donation limit can be "presumptively redesignated" to the general election.
The odd feature of this congressional election - where a special and a general occur the same day - calls for some FEC interpretation.
