Final answer:
The Republican Party's alliance with evangelical voters, white southerners, and the wealthy in the 1990s is an example of a party coalition, which signifies the grouping of various demographic and interest groups in support of a political party.
Step-by-step explanation:
In the 1990s, the Republican Party primary drew support from evangelical voters, white southerners, and the wealthy. This is an example of a party coalition. A party coalition refers to the alliance of distinct interest groups and demographics that come together to support a political party. The Republican coalition during this period was often characterized by a merger of different backgrounds and perspectives, including those holding conservative and pro-business economic policies, as well as socially conservative goals such as opposition to abortion and affirmative action.
Such alignments are vital to understand the realignment of political allegiances that happens over time, representing shifts in the party's base of support. During the 1980 presidential election, for instance, the rise of the evangelical movement in politics was a key factor in the shifting allegiances, moving support from Jimmy Carter to Ronald Reagan.
Understanding these coalitions is essential in comprehending the dynamics of political power and the changing landscape of American politics.
