Nikki Haley is the definition of a waffling, unprincipled snowflake. She's never done a thing just because it was the right thing to do: as gov she literally had to be repeatedly shamed into taking down Confederate flags and statues. It only happened when it was just too politically untenable.
But the thing about her racism is that it is so self loathing, and the clearest evidence of that comes when she attacks--pretty viciously--VP Harris. She tries to dress up in legitimate discourse, but just listen to her. And she is curious in her assaults given that Haley and Harris have so much ethnically in common, so that particular thing feels oddly creepy.
And she's cowed by Trump. What a lackey.
