No Free Campaigns for Congress Act of 2018 This bill excludes from treatment as franked mail material transmitted by a Member of Congress, or a Member-elect, that includes a photograph or photographic representation, other than as an electronic communication. The total amount that may be spent for the costs of franked mail sent by any Member or Member-elect may not exceed $10,000 during a calendar year or during a fiscal year in the case of the House of Representatives or the Senate, respectively. The bill bans mass mailings postmarked at any time during an election year. The franking privilege may not be used for mail that is purely related to a campaign for election for office.
