Due to the history of the US, race is highly determinate to culture and socioeconomic status. It's a very good proxy for to cut across all sorts of differences. For example, you mentioned home owners. Guess which race has very few of those?
I would have preferred to see a poll based on income, but race is still a decent proxy for that.
