Early in the 19th century the party of Jefferson, the Republicans, then the Democrat-Republicans, became the Democratic Party. They supported slavery and a new Republican Party, led by Abraham Lincoln, set out to destroy slavery. Even as late as the 1940s, the Democrats fought against every Republican effort to pass Anti-lynching laws. That says all you need to know about Democrats. Their present tactic, as exemplified by Ocasio- Cortez is pandering to Blacks.
