Simulation:
You are the leadership of a party that does not win and does not control any house or branch of government.
You were routed by a demographic that you treated as an enemy that still holds a lot more electoral power than you estimated, and now suspects you are an organized agency attempting to deliver their genocide due to their race.
Your generational achievement and icon was a 'black' president who did not effect security nor prosperity, and rather than take the peoples invitation to unite, instead executed social policy that represented stereotypical race fears about a black man in charge.
His legacy is helplessly falling apart day by day at a ferocious pace that assures its absolute extinction far faster than was imagined possible. In the near future, he will be little more than a footnote and of no use politically, but rather the symbol of all your liabilities with the average voter.
You conclude he is no longer any use to you. Instead, his name alone will cripple your goals for at least a generation from the chaotic memories he evokes. You learn his base was loyal to his race only, not the party. New scandals are breaking that may expose him in numerous, gross malfeasance charges soon and you could not save him now if you tried anyways.
Would you try to throw him under the bus faster than the opposition can destroy him as a sacrifice to show the electorate you have changed, to distance yourself as much as possible as the fastest way to redefine your party identity to the electorate that may otherwise never trust your brand again?
