If Sanders get the nomination, then good luck to him beating Trump. He certainly won't be getting the votes of many African-American voters who have no attachment to him.
There is making a case in good faith that Sanders is not the most electable candidate.
And then there is descending into absurdities.
Like I said, the last three Democratic Presidents were from states with higher than average African-American populations. The biggest losers were from states below the nationwide average.
So, I guess Donald Trump is elected on a wave of afroamerican support from the state of New York
