The black face thing made him a pawn of the left. He is now virtue signaling his way back into their good graces.
"Oh, what a tangled web we weave, when first we practice to deceive!" (Sir Walter Scott, 1808).
My Mammy song by Joe Young and Sam M. Lewis (Al Jolson sang in blackface but was actually introduced in 1918 by William Frawley who was Fred Mertz in I Love Lucy)
Mammy, Mammy, I'm comin',
I'm so sorry that I made you wait!
Mammy, Mammy, I'm comin'!
Oh God, I hope I'm not late!
Look at me, Mammy! Don't you know me?
I'm your little baby!
I'd walk a million miles
For one of your smiles,
My Mammy!
