In modern America, a war of secession could be caused if some states concentrated on concepts focused on Republican or Democratic ideas. This is because, as we know, these two political aspects have very different, contrasting and adverse ideologies.
Supporters of both ideologies regularly see themselves as hostile and fail to dialogue in a coherent way, highlighting the positive points of each of them and disapproving the negative points that each has. This hostility can trigger tension, which could trigger a secession war if there was a concentration of Republicans in some states and a concentration of Democrats in others.
As we know, the south of the country has a predominance of citizens favorable to republican ideas. Although I do not believe in a possible war of secession today, we can imagine a situation where the concentration of Republicans in the south, generate hostility with the Democratic parties that trigger a second war of secession.
