Right--even if the person does have some of the same experiences you'd have to make sure that translated into a similiar view on how to address them. And then that would have to translate into policies you wanted to vote for. If you're a white male you might (or might not) prefer voting for someone also white and male. But you wouldn't assume that any white male is going to agree with you. You're used to having a variety and a choice of white males to vote for.
