Contributions to Presidential Candidates
An individual may contribute up to $2,500 (multicandidate PAC: $5,000) to a Presidential candidate in the primary election campaign, whether or not the candidate accepts matching funds. (The $2,500 limit applies to the entire primary process, rather than to a single primary held in a particular state.) The primary election period ends on the date that the candidate accepts the nomination of the party. (For Republicans, that date will be 8/30/12, and for Democrats, that date will be 9/6/12.)
