Why did people on each side of the slavery issue want the most voters in kansas?

In Kansas, both pro-slavery and anti-slavery factions sought to increase their voter base to influence the outcome of whether the territory would allow slavery. Pro-slavery advocates wanted more voters to ensure that Kansas would join the Union as a slave state, thereby expanding the institution of slavery. Conversely, anti-slavery supporters aimed to boost their numbers to prevent the establishment of slavery in Kansas and promote free-state principles. This struggle for voter dominance was pivotal in shaping the political landscape and escalating tensions leading to violent conflicts known as "Bleeding Kansas."
