doesn't strike me as someone who could possibly appeal to WWC at all
That won't be necessary.
WWC are not the base of the Democratic Party. Chuck Schumer and Tom Perez have made a giant blunder in trying to reach out to racist, misogynist Trump supporters. With Kamala Harris she is going to excite the Obama coalition and have those coattails be helpful in defeating Trump. We should be targeting voter suppression and get the vote out in communities that have been threatened by Republican tactics, not a group of white people who have voted in a white supremacist.
