Any expenditure that is not directly related to the candidate's election campaign is prohibited.
Candidate campaign contributions may not be used to defray non-reimbursed expenses related to public office, or for charitable donations, club memberships, newspaper subscriptions, constituent gifts and entertainment or other miscellaneous expenses that are not directly campaign- related.
Campaign contributions may be used to cover earnings lost as a result of campaigning, or to pay for child care if the expense would not have occurred but for the campaign, and in other specific circumstances.
