Why Can't Third Party Candidates Win? | NBC News Signal

Overview

The video explains why third-party candidates struggle to win U.S. elections, using Larry Sharp’s Libertarian campaign for New York governor as a case study.

New York as an Example (Cross-Issue Appeal, Low Odds)

• Sharp’s campaign is described as trying to appeal to voters across party lines.
• The segment notes his positioning as:
  • Pro-legalization of marijuana
  • Supportive of gun owners
• Despite this broader appeal, the campaign is framed as unlikely to succeed—polling and fundraising do not appear to translate into victory.

The Structural Problem: “Duverger’s Law” and Winner-Take-All Elections

NBC News interviews Donald Green, a political science professor at Columbia, who argues that the electoral system strongly shapes which parties can realistically win.

• In winner-take-all systems:
  • Third parties are effectively disadvantaged.
  • Even if they receive a significant share of votes, they may win no seats.
• This contrasts with proportional representation, where vote share more directly becomes seat share.

Money and Media Aren’t the Main Barrier

Although viewers might assume third parties lose primarily due to limited funding or coverage, Green says:

• Funding is only a small part of the challenge.
• The electoral design is the larger obstacle.

Voter Perception: “Outsiders” and Protest Votes

The commentary suggests many Americans view third-party candidates as:

• Outsiders
• Options for protest voting

This contributes to the idea that voting third-party can “do more harm than good” by drawing votes away from major-party candidates.

“Spoilers” and Historical Echoes

The video highlights the spoiler argument using historical examples:

• Ralph Nader (Green Party) in 2000
  • Framed as siphoning support from Al Gore
• Teddy Roosevelt (Bull Moose Party) in 1912
  • Framed as helping elect Woodrow Wilson

Campaign Mechanics and Ground-Level Limits

Sharp’s campaign strategy is described as:

• Grassroots
• Relentless messaging, including live-streaming and repeated town-by-town engagement

However, an anecdote points to limited turnout at events, illustrating how difficult it is to build momentum outside the major-party ecosystem.

Why Supporters Still Choose It

The segment includes supporters who say:

• They feel shut out of meaningful choices beyond Democrats and Republicans.
• Some express that long-term loyalty is ending because it has been “so hard” for non-major-party candidates to succeed.

Core Framing

Even if third-party voters believe their vote is meaningful or morally necessary, the video argues that:

• The system’s structure
• Plus the spoiler narrative

make it extremely difficult for third parties to convert support into wins.
