Scholars refer to a period when a major lasting shift occurs in the popular coalition supporting one or both parties as what?

• A. Transitional phase.
• B. A critical election or realignment period.
• C. Era of discontent.
• D. Era of good feelings.

Answer: (B)

This concept is realignment, a period when a major, lasting shift occurs in the popular coalition supporting one or both parties. During a realignment, the groups that reliably back each party change—new demographics or issue priorities realign with a different party, and the political landscape moves to a new dominant coalition that endures for a generation or more. Realignments are typically sparked by broad upheavals—economic crises, social transformations, or large-scale demographic changes—and they set the stage for a new party system and policy agenda rather than just a single election result.

The other terms don’t fit this idea as well. A transitional phase isn’t the standard label scholars use for lasting coalitional changes, and eras like “era of discontent” or “era of good feelings” refer to more specific historical moods or periods rather than a durable shift in party coalitions.
