The Dems need to check off as many aggrieved groups as possible. Kamala Harris will be the nominee (black, female, Communist) and Pete Buttgag will be the veep nominee (he's a white male but gets bonus points for being gay, married, and Communist).
Dems need a cleansing and some. Creating an out of control sub group has really gotten the best of them.
President Trump will have a field day with all these lackluster nominees
