The Democrats effectively split into two camps, with both the Chivalry and Free Soilers nominating their own candidates for the 1853 election. By 1857, the party had split into the Lecompton and Anti-Lecompton factions. Lecompton members supported the Kansas Lecompton Constitution, a document explicitly allowing slavery into the territory, while Anti-Lecompton faction members were in opposition to slavery's expansion. The violence between supporting and opposition forces led to the period known as Bleeding Kansas. Splits in the Democratic Party, as well as the power vacuum created by the collapse of the Whig Party, helped facilitate the rise of the American Party both in state and federal politics. In particular, state voters voted Know-Nothings into the California State Legislature, and elected J. Neely Johnson as governor in the 1855 general elections.
