Bad analogy. Better one would be if the Democratic party started to put up statues to Jefferson Davis because the Democratic Party members who were children/grandchildren of Jefferson Davis wanted to re-rehabilitate the image of Jefferson Davis.
I promise you that if the Democratic party started trying to retroactively white wash the confederacy, or specific subsets of the confederacy, in the same exact way the Ukrainians are, that the people that were oppressed by the Democratic Party would no longer vote for them.
