Political suicide is the concept that a politician or political party would lose widespread support and confidence from the voting public by proposing actions that are seen as unfavourable or that might threaten the status quo. A politician who committed political suicide might be forced to resign. A political party could stand to lose followers by deviating greatly from its core values and policies. Another term for such policies are "the third rail".
Cynics may blame this concept as a reason for a lack of real change or progress in society and that actions described as political suicide are usually sound intentions shot down by reactionism and fear of change.
