There is one problem with this article - it only goes back 70 years. The Democrats have been on an unprincipled quest for political power and dominance since before the Civil War. And certainly after the Civil War, their goal was power by any means including violence, whipping up racial hatred (back then, against blacks) and oppression. They are a cancer on the country.
it only goes back 70 years
Actually 65 years since January 1961. My whole lifetime. There was virtually no other parties until just before the civil war, so it is a bit of hyperbole to reference before the war.
