Final answer:
The information provided does not specify how Abraham Lincoln influenced Alexander Coffroth's vote. It instead outlines Lincoln's general political strategy during his presidency, such as his refusal to compromise on slavery in the territories while also exploring forms of governance and suffrage that could unify various factions.
Step-by-step explanation:
The question revolves around how Abraham Lincoln was able to influence Alexander Coffroth's vote. However, the information provided does not specifically detail the methods or mechanisms used by Lincoln to persuade Coffroth. Instead, the supporting texts discuss Lincoln's broader political strategies and actions during his presidency, including his stance on black suffrage, the Crittenden Compromise, the drafting of new state constitutions, and his positions on slavery and the Union.
Lincoln's approach to securing support for his policies often involved a combination of refusal to compromise on certain principles, such as the non-extension of slavery into the territories, while also demonstrating a willingness to entertain certain forms of suffrage and governance that could appeal to different factions within the Union. Furthermore, patronage power was another influential tool as demonstrated by General Nathaniel P. Banks, and it could be speculated that Lincoln may have used similar methods in other instances.
