Yes, you have the right wingers throwing out "whore" for no reason, for saying her mothers name should be enough to disqualify her...

Now these people are too far gone to get any hope of their vote to be sure, however I suspect milder versions of those sentiments lie perhaps even subconsiously in some moderate voters. They may feel vaguely "uncomfortable" and doubling down might just exacerbate that while a milquetoast white dude might alleviate that discomfort.
