The 1860 United States presidential election was the 19th quadrennial presidential election, held on Tuesday, November 6, 1860. In a four-way contest, the Republican Party ticket of Abraham Lincoln and Hannibal Hamlin[2] won a national popular plurality, a popular majority in the North where states had already abolished slavery, and a national electoral majority comprising only Northern electoral votes.
Republicans were a third party to the Democrat-Whig two party system. Republicans weren’t on the ballot across the south.
You threw the election with this approach. You need to understand that.
This exact approach to rhetoric and myopic view of what is possible just handed the government over to fascism.
Name one national election in the history of the US where voting third-party resulted in the goals of those voters being achieved.
