In 1860 free state voting populations were larger than those of slave states so these states, as a total, had more Electoral College votes than slave states. One of the catalysts to the U.S. Civil War was the election of Abraham Lincoln over John C. Breckinridge. Lincoln took office in January 1861 and the war started in April of 1861. Abraham Lincoln was not on the ballot of ten slave states but still won the election of 1860 because he won the largest number of Electoral College votes. Seven of these slave states, unwilling to accept the results of the election, decided to secede from the United States.
Several states considered seceding from the United States over the 2016 presidential election. Oregon, California, and Silicon Valley threatened to secede after Hillary lost. Texas was discussing secession if Trump lost. Canada offered to make several U.S. States part of Canadaif they left the United States.
Since the election of Donald Trump to President of the United States, we have seen an escalation of violence. Therapists have increased business because progressives did not have their way in the 2016 election. Many progressives are unable to cope with reality and instead choose to live in a fantasyland. Even before the 2016 election, we witnessed how nasty, aggressive, despicable, and violent progressives have become and these behaviors have escalated since Hillary Clinton lost the 2016 election.
The election of Donald Trump has brought to the fore the stark difference between ideological, economic, political, and social ideas. His election exposed many politicians as the traitors they really are.
There are more divisions now and larger divisions in the United States than in the 19thCentury. The philosophical lies of progressives did not have a strong following until the 20thCentury. We are witnessing the division and the weakness these progressive ideologies create. Progressive ideologies make people weak and afraid.
That being the whole idea behind the evil ideology, of course. Lots more here; read it all.
