Poor white people vote GOP everywhere because muh culture war.
That's simply not true.
You're assuming that all poor whites are some rural "white trash" stereotype out of IceSpear's mind. There's in fact many poor whites in urban areas too, many of whom are not socially conservative at all. Think of single mothers, recent college grads who haven't landed a good job yet, LGBT people who aren't upper class, etc. Not to mention that a lot of these type of people can't hold a job or get a high paying job because of personal issues and mental illness, this is actually pretty common amongst intersectionalist feminists.
To answer the thread question, Democratic, like all other people in Minneapolis.
Obviously I know poor white people in urban areas vote Democratic. I was being hyperbolic (seems we've had this conversation before).
