Party Realignment in AP US Government

The election is the moment, the realignment is the decades after

Calling 1932 "the realignment" gets the term slightly wrong. The 1932 election was a critical election, one contest where voter support visibly shifts between the parties. Realignment is the lasting pattern that contest reveals or kicks off.

A useful test is time. A question can name a single election year without describing a critical election. If it points to a particular election associated with a lasting shift in party support, it may be describing a critical election, so look for evidence that the shift persisted. If it describes groups of voters staying with a new party through election after election, it's describing realignment.

AP US Government links the two directly. Topic 5.4 describes critical elections as contests marked by realignment and says they've reshaped how parties are structured. So the two terms work as a pair: one names the event, the other names the change it locks in.

1932 and the New Deal Coalition as your strongest example

In 1932, during the Great Depression, Franklin Roosevelt won the presidency, and Democrats became the majority party in national politics for decades. That election is the critical election. The realignment is the coalition that formed around Roosevelt's New Deal programs and held together for decades.

The New Deal Coalition brought together urban workers, union members, immigrants and their children, white Southerners, and, over the course of the 1930s, African American voters, who had mostly backed Republicans since the Civil War. That last shift is a good reminder that realignment can keep unfolding after the critical election itself.

A second example happened gradually. After the civil rights laws of the mid-1960s, white Southern voters moved from the Democratic Party toward the Republican Party over several decades. The change took many elections to finish, but it still counts as realignment because whole blocs of voters changed parties and stayed. This example also helps explain the political polarization of later decades, as each party's coalition became more ideologically uniform.

Realignment versus dealignment and one-time swings

Wrong answer choices often describe something that looks like realignment but isn't.

• Dealignment is when voters weaken their ties to both parties, with more people calling themselves independents or splitting their tickets. Voters drift away from parties instead of moving to a new one.
• A one-election swing, like a state flipping for a popular candidate and flipping back four years later, has no lasting coalition change.
• A strong third-party showing in one race can signal frustration with the major parties, but it doesn't reshuffle their coalitions on its own.

Dealignment ties into another part of Topic 5.4, the rise of candidate-centered campaigns. When voters focus on a candidate's personal traits instead of party labels, party loyalty loosens. Split-ticket voting associated with dealignment is also one reason divided government has become common.

How Topic 5.4 uses realignment to explain why parties change

The Democratic Party of the 1920s and the Democratic Party of today share a name but rest on very different voters, and Topic 5.4: How and Why Political Parties Change and Adapt (Unit 5, Political Participation) asks you to explain shifts like that. The topic covers why parties shift and how they do it. Realignment is the biggest-scale answer.

Realignment involves both voters and parties. Voters move, and parties respond by reshaping their policy positions and messages to attract the demographic groups they need. The essential knowledge says parties may change their platforms to win over different coalitions, and realignment is what happens when those changes, plus events like a depression or a civil rights movement, permanently reshuffle each party's base.

This also explains why a party's name can outlast its coalition. The Democratic Party of the 1920s and the Democratic Party of today share a label, but the voters behind them are very different.

Spotting realignment in a party-identification graph or scenario

An answer choice that says voters shifted for one election and flipped back is describing a one-time swing, and one that says voters left both parties is describing dealignment. For realignment, look for the word that signals duration: lasting, durable, long-term, or across several elections. Choices built around a single result usually point to a critical election instead.

Stimulus sets and Question 2 (Quantitative Analysis) can give you a line graph of party identification or congressional seats by region over time. If one party's share among a group falls steadily while the other's rises, and the change holds, describe it as a realignment. Name the trend, give the direction and approximate time period, and then connect it to a reason, such as parties repositioning on policy to win new coalitions.

For Question 1 (Concept Application), a scenario might describe a group of voters moving toward a party over several cycles. A strong answer identifies the shift as realignment, explains why it counts (lasting change in coalition support), and explains an effect, such as a party changing its platform or a new majority party taking control of Congress.
