Why do some scandals topple governments while others barely dent a politician’s career?
Scandals expose corruption, lies, or abuse of power, and they almost always shake public trust.
Some force resignations or inspire new laws. Others reveal how deeply partisanship shields leaders from fallout.
In this blog, I’ll show you how political scandals influence elections by examining significant cases from the 20th and 21st centuries.
Each one reveals what happened, how it reshaped politics, and how elections and voter behavior shifted.
These stories prove scandals are more than headlines; they are turning points in democracy.
How Political Scandals Influence Elections?
Political scandals have shaped governments and voter trust across decades. These examples show how controversies shifted campaigns and election results.
1. The Enron Collapse and U.S. Politics (2001)
Enron was once praised as a model of corporate innovation.
Executives Jeffrey Skilling, Kenneth Lay, and Andrew Fastow created a massive accounting fraud that hid debt and inflated profits.
When the company collapsed in 2001, it was the largest bankruptcy in U.S. history.
Thousands lost jobs and pensions, and investors were wiped out.
Impact on Politics and Laws
Enron had close ties to Washington.
Its collapse triggered hearings about corporate money in politics and weak regulation.
Congress responded with the Sarbanes-Oxley Act of 2002, a law that tightened accounting rules and increased penalties for fraud.
Voters’ Reaction After the Scam
In the 2002 midterms, Enron became a symbol of unchecked corporate power.
Candidates campaigned on ethics, accountability, and tougher oversight.
Voters began questioning the influence of corporations in politics, reshaping debates for years to come.
2. The Jack Abramoff Lobbying Scandal (2006)
Lobbyist Jack Abramoff used gifts, luxury trips, and donations to bribe lawmakers.
He pushed them to pass laws favoring his clients, including casino interests.
The scheme unraveled in the mid-2000s, and Abramoff pled guilty to fraud, tax evasion, and bribery.
Several lawmakers were investigated, convicted, or forced to resign.
Impact on Politics and Laws
The scandal exposed how lobbying distorted U.S. politics.
Congress passed reforms limiting gifts from lobbyists and tightened disclosure rules. “Abramoff” became shorthand for corruption.

Known as Operation Car Wash, this scandal revealed how executives at state oil company Petrobras funneled billions through inflated contracts and kickbacks.
Politicians across parties were implicated, including former president Luiz Inácio Lula da Silva.

The investigation lasted years, uncovering systemic corruption in Brazil’s political and business elite.
It led to new laws on procurement and corporate transparency, while judges and prosecutors gained greater prominence.

In 2018, it was revealed that Cambridge Analytica harvested Facebook data from millions without consent.

Impact on Politics and Laws
The leak sparked global outrage, leading to investigations, resignations, and tax reform debates.
Governments pledged to crack down on tax havens and increase financial transparency.

In Iceland, public anger forced Gunnlaugsson to resign, and voters turned toward parties that campaigned on ethics.
Elsewhere, corruption became a top election issue, fueling skepticism toward elites.
6. Watergate Scandal, U.S. (1972–1974)
A break-in at the Democratic National Committee headquarters revealed a pattern of illegal activities tied to President Richard Nixon’s reelection campaign.
Cover-ups, wiretapping, and political sabotage came to light. Though Nixon won reelection in 1972, mounting evidence forced his resignation in 1974.
Impact on Politics and Laws
Watergate led to reforms in campaign finance, greater limits on executive power, and stronger oversight of government agencies.

“Watergate” became shorthand for political scandal itself.
7. Access Hollywood Tape, U.S. (2016)
A 2005 tape surfaced in October 2016 showing Donald Trump making crude remarks about women.
Released just weeks before the election, many thought it would end his campaign.

The tape fueled national debates about sexism, media coverage, and accountability.
Both parties faced questions about character and standards for candidates.

The scandal fueled debates about transparency and accountability in Congress.
While no sweeping laws followed, media scrutiny of congressional perks grew.
Voters’ Reaction After the Scam
The scandal fed a “throw the bums out” mood.
Many incumbents retired or lost, and voters elected a wave of new lawmakers.

10. SNC-Lavalin Affair, Canada (2019)
