Campaign funds may only be used for expenditures that are directly related to the candidate's campaign. Although by no means a complete list of allowable campaign expenses, the following will give you an idea of typical campaign expenses:
Further, although the law prohibits using campaign funds to make a contribution to another candidate or political committee (other than using surplus funds to give to a political party or caucus committee), it is OK for a candidate to use his or her campaign money to attend an event held by another candidate, a political party or committee so long as attending the event is directly related to the candidate's own campaign and the candidate's campaign only pays the per-person cost of consumables provided at the event. That is, the candidate uses his or her campaign money only to pay for his or her share of the actual cost of food, beverages, preparation, catering and entertainment furnished at the event. If the candidate wishes to pay the full admission charge, he or she must use his or her personal funds to do so.
