Lincoln was not very popular until revisionist changed the narrative….
He was so hated in the North that the New York Times editorialized a wish that he would be assassinated. This is perfectly understandable: He illegally suspended Habeas Corpus and imprisoned tens of thousands of Northern political critics without due process; shut down over 300 opposition newspapers; committed treason by invading the Southern states (Article 3, Section 3 of the Constitution defines treason as “only levying war upon the states” or “giving aid and comfort to their enemies,” which of course is exactly what Lincoln did).
He enforced military conscription with the murder of hundreds of New York City draft protesters in 1863 and with the mass execution of deserters from his army. He deported a congressional critic (Democratic Congressman Clement Vallandigham of Ohio); confiscated firearms; and issued an arrest warrant for the Chief Justice when the jurist issued an opinion that only Congress could legally suspend Habeas Corpus.
He waged an unnecessary war (all other countries ended slavery peacefully in that century) that resulted in the death of as many as 850,000 Americans according to new research published in the last two years. Standardizing for today’s population, that would be similar to 8.5 million American deaths in a four-year war.
