Abstract

Throughout the nineteenth century, political parties attempted to mediate local, state, and national conflicts to forge a winning electoral coalition. The question here is whether party leaders felt that success depended on offering clear divergent positions to their voters. In other words, to what extent did the parties present alternative programs to the electorate—at any specific time or over time? This study examines the growth of the two-party system in nineteenth-century America by focusing on the interaction of the elites of the Democrats and Whig/Republicans in forging their electoral message. The methodology includes a content analysis of national and state party platforms during presidential election years 1840 through 1896 to show when and where parties emphasized certain issue proposals. Ultimately, this is a story of interparty polarization—over time, the two major parties tended to emphasize the same issues and offer divergent positions in their platforms.

FIGURE 1 Difference in average salience of all the issues between the National Democratic and Whig/Republican Party platforms and the state Democratic and Whig/Republican Party platforms, 1840–96. Note: The trend lines indicate the absolute difference in the average platform issue salience between the Democratic and Whig/Republican parties in each state and on the national level from 1840 to 1896. The smaller the difference in average issue salience, the more alike are the parties on each level in what issues are represented and to what degree in the platforms.

FIGURE 2 Positional salience of issues—tariff, state’s rights, and internal improvements—between the Democratic and Whig/Republican party platforms—state and national, 1840–96. Positional salience refers to the combination of the position and salience of an issue in each platform. Each issue is paneled to gauge party polarization of the Democratic and Whig/Republican parties from 1840 to 1896. The national trend lines simply denote the positional of each party on the issue in each election. The state trend lines represent the mean of the positional salience of the issue across the state party affiliates.

FIGURE 3 Variance in salience of all the issues between the Democratic and Whig/Republican Party platforms—state and national, 1840–96. The trend lines indicate the variance around the mean of the platforms in each election year of the Democratic and Whig/Republican parties from 1840 to 1896. The “average (all issues)” line represents a composite calculation of the means for each issue in each platform in a year. The “average (without economics)” line follows the same procedure but excludes economic issues from the calculation. The lower the point in the line, the more similar is the platform content of the parties. A spike in the line indicates dissimilarity in platform content. The major trend line is derived through a calculation of the mean and standard deviation of each domain in each election year to yield an average weighted standard deviation for that year.
