I know literal meaning of 'go home'. In the following talk it's vague to me.
“Let me guarantee you this, based on everything that I know and understand, and the help that [Biden] has already gotten from the Black community ... he can’t go home without a Black woman being VP,” Waters said. “We’re going to have a Black woman VP.”
Waters insisted that Biden needed a black woman vice president. If so, does 'go home' mean 'go to White House' and not his own real home? I can't find that the phrase means 'succeed' in any dictionary.
