The Free Soil Party essentially merged into the Republican Party after 1854. Like their Free Soil predecessors, Republican leaders in the late 1850s generally did not call for the abolition of slavery, but instead sought to prevent the extension of slavery into the territories. The Republicans combined the Free Soil stance on slavery with Whig positions on economic issues, such as support for high tariffs and federally-funded infrastructure projects. After 1860, the Republican Party became the dominant force in national politics. Reflecting on the new electoral strength of the Republican Party years later, Free Soiler and anti-slavery activist Henry Brewster Stanton wrote that "the feeble cause I espoused at Cincinnati in 1832...rested on the broad shoulders of a strong party which was marching to victory."
