There's no reason for Obama to do it - the working-class/Hispanic problems he will have are not going to be remedied by a black man/white woman ticket. In fact, they may worsen with that ticket.
The problem with this argument is that we are not talking about some generic white woman politician -- we are talking Hillary Clinton. And she has already abundantly shown her ability to win both working class and Hispanic voters. Working class white women in particular are one of her very best demographics. She has a strong, longstanding reputation within the Hispanic community and many working class people remember better economic times under the Clinton Administration.
