Answer:
He refused to do anything.
Explanation:
Franklin Pierce was the United States President between 1853 to 1857. His administration was marred by a lot of controversies particularly the event known as Bleeding Kansas.
In 1855 during the election to determine if Kansas were to be added as a Slave state or not, the process was marred by fraud and eventually led to violence.
However, instead of doing anything about the violence, "Pierce refused to do anything." He chose to let the politics of Kansas be resolved by the residents, even though it was believed to lend toward the pro-slavery side.
