Haven’t you heard the latest liberal/progressive/communist lie?
Lincoln was a liberal, Douglas was a Conservative. The Republicans are and have always been racist, but the parties “flipped” (at some mythical point) so Democrats are falsely being attributed as the racists in history.
Indeed the entire "Southern Strategy" was a vicious lie fabricated by the marxists. In reality, the Republicans of the 1860s have the same principles of the non-RINOs of today: small government, low taxes, pro-business and color-blind liberty for all.
So what was Breckenridge... he was the candidate of and choice of the South...
