From Disagreement to Distrust

The United States has grown more polarized since the 1970s, with especially rapid increases during the 2000s. Urban and suburban areas have generally become more Democratic, while agricultural rural areas have become more Republican.

Two Kinds of Polarization

Ideological polarization means the parties increasingly disagree about policy. Affective polarization goes further: people dislike and distrust members of the opposing party. According to the cited research, this emotional divide is stronger than in comparable democracies.

The shift has been asymmetric. Congressional Republicans moved substantially to the right, while Democrats moved leftward more modestly, though the Democratic Party shifted left on social and cultural questions after the early 2010s.

Winning the Base

Party strategists increasingly focus on mobilizing loyal supporters rather than persuading undecided voters. Candidates may avoid debates, town halls, diners, and state fairs in favor of friendly partisan settings and fundraising events. These safer environments reduce the chance of confrontation—but also reduce public accountability.

When Losing Is No Longer Accepted

A democratic system depends on losing candidates and supporters accepting legitimate results. Yet a growing movement within the Republican Party has refused to commit to accepting defeat. The trend became especially visible after the 2020 presidential election and the violent January 6, 2021 attack on the Capitol aimed at stopping certification.

Election denial transforms competition into a threat to be defeated rather than a contest whose outcome must be respected. Once that norm weakens, every election can become a constitutional crisis.

The danger of polarization is not simply that citizens disagree. It is that they may stop believing that political opponents are legitimate participants in the same democracy.
