So, what is she going to do? Double down on easily verifiable facts? Will she try to rewrite history, maybe try to justify attempts by the Ukrainian nationalists at ethnic cleansing? Perhaps she can hide the Ukrainian complicity in the Holocaust in the German occupied Ukraine? The only way she can come out of this with any credibility is by being upfront about established and verifiable history. Having a Jew hating grandfather does not make you one. Hiding that fact makes you a suspect.
