flip-floppers

Flip-floppers are people who repeatedly change their position on an issue, especially in politics.

The term is almost always pejorative, suggesting the person lacks conviction or principle and shifts their stance based on convenience or popular opinion rather than genuine reconsideration.

Voters don't trust flip-floppers who say whatever they think people want to hear.

The singular flip-flopper is more common, typically leveled at a specific politician during a campaign.
