A Black American explains why he is a Republican

Black Americans were solid Republican until the 1932 election when FDR and the Democrats swept the country. I’ve never found a good explanation for why Blacks made such a sudden switch from the party that led them out of slavery, to join the party that was willing to fight a long civil war to keep them in slavery and when that didn’t work immediately re-instituted a new form of slavery with Jim Crow laws. This video looks good in full screen.
