Background
Under the provisions of the New York Constitution of 1846, 32 Senators were elected in single-seat senatorial districts for a two-year term, the whole Senate being renewed biennially. The senatorial districts (except those in New York City) were made up of entire counties. 128 Assemblymen were elected in single-seat districts to a one-year term, the whole Assembly being renewed annually. The Assembly districts were made up of entire towns, or city wards, forming a contiguous area, all in the same county. The City and County of New York was divided into four senatorial districts, and 16 Assembly districts.
At this time there the Democratic Party was split into two factions: the Hard-Shells (or Hards) and the Soft-Shells (or Softs). In 1848, the Democratic Party had been split into Barnburners and Hunkers. The Barnburners left the party, and ran as the Free Soil Party, with presidential candidate Martin Van Buren. Afterwards the larger part of the Free Soilers re-joined the Democratic Party. During the following years, the Hunkers split over the question of reconciliation with the Barnburners. The Hards were against it, denying the Barnburners to gain influence in the Party. The Softs favored reconciliation with the intention of maintaining enough strength to win the elections. Both Hards and Softs favored a compromise on the slavery question: to maintain the status quo and to leave the decision to the local population in new Territories or States if they want slavery or not, as expressed in the Kansas-Nebraska Act.
The anti-slavery faction of the Whig Party, the "Free Democrats" (former Barnburners and Free Soilers), and the short-lived Anti-Nebraska Party merged into the Republican Party.
Most of the Whigs which favored a compromise, or preferred to sidestep the issue, joined with parts of the Democratic factions the Know Nothing movement which ran in the election as the "American Party."
