Third rail (metaphor)

From Wikipedia, the free encyclopedia

This third rail, used to power trains, carries hundreds of volts of electricity, resulting in a spectacular electrocution and likely death for anyone who touches it. Third rail political issues are similarly "charged".

The phrase third rail is a metaphor in politics to denote an idea or topic that is so "charged" and "untouchable" that any politician or public official who dares to broach the subject would invariably suffer politically.

The third rail in a train system is the exposed electrical conductor that carries high voltage power. Stepping on the high-voltage third rail usually results in electrocution. The use of the term in politics serves to emphasize the "shock" that results from raising the controversial idea, and the "political death" (or political suicide) that the unaware or provocative politician would encounter as a result.

Disagreement may occur over whether a specific issue is a "third rail" issue. Nonetheless, the following examples are often "third rail" issues in the United States:

• Raising taxes
• Eliminating or radically reducing the scope of a major social program, like social security, welfare, or the healthcare system
• Cutting funding for law enforcement
• Creating a National Identity Card
• Ending support for certain allied countries
• Legalization of controlled substances
• Suggesting that race and crime are related
• Suggesting that certain religions or faiths are closely tied with violence

Third rail issues usually only die when politicians who have proven their credentials on related matters ignore the taboo and openly challenge the controversial issue. For example, ending recognition of the Taiwanese government in favor of the Communist People's Republic of China was long a third rail issue in the United States, until Richard Nixon openly began to establish ties with the PRC. The consensus was that since Nixon had proven himself to be a staunch anti-Communist on other major issues, he could "get away" with doing something that would otherwise appear to be a very pro-Communist gesture. The saying "Only Nixon could go to China" has become a popular explanation of how third rail issues die.

[edit] Popular Culture

• Social security reform is referred to as a third rail issue in the TV show The West Wing (Episode 12, Season 5 - "Slow News Day"), leading Toby Ziegler to retort, "that's 'cause the third rail's where all the power is."
