Instead of settling the slavery controversy, the Dred Scott decision intensified it. Meanwhile, the proslavery forces, having won legalization of slavery in the territories, moved to ensure that it would remain legal when Kansas became a state. The required deft maneuvering, because legitimate antislavery settlers outnumbered proslavery settlers by more than two to one. In 1857 the proslavery legislature (elected by the fraudulent votes of border ruffians two years earlier) called for a constitutional convention at Lecompton to prepare Kansas for statehood. But because the election for delegates was rigged, Free Soil voters refused to participate in it. One-fifth of the registered voters thereupon elected convention delegates, who met a Lecompton and wrote a state constitution that made slavery legal.
