No it really isn't, she still claims NA heritage based on some ridiculous one drop rule despite Cherokee Nation, six years ago, literally telling her based on genealogy that she clearly isn't NA and yet she still doubled down on it and didn't adopt any of their customs or do any of the things that are required to gain tribal membership. So why exactly is she still peddling it despite the fact that she hasn't even shown the slightest amount of interest in the affairs of natives or during the DAPL protests? Why did she make up the story about her parents having to elope? Why did she put her heritage as Native American on the bar application despite it supposedly not being used to benefit her in any way? And keep in mind she'd be going against Trump who is going to use the anger over people benefiting from affirmative action to suppress enthusiasm for her in a country that literally just voted for him four years ago. You'd have to have blinders on to not see this as a potential threat to her candidacy and given that you're her prime demographic it's not shocking.
On the flip side you potentially have, "old man got basic medical procedure a year ago and is fine", which is actually very easy to explain.
