Whistle stoppers are typically defined as people who engage in political campaigns, making brief appearances at different locations to give speeches or rallies. There are a number of synonyms for the term, including stumpers, campaigners, politickers, and canvassers. Each of these terms carries a slight nuance of meaning, with stumpers suggesting a more combative or aggressive approach to campaigning, while canvassers may focus on grassroots organizing and forming personal connections with voters. Politickers is a somewhat more negative term that implies a certain amount of scheming or manipulation, while campaigners is a more neutral and straightforward term that simply denotes someone running for office.
