Bleg: Who Has Data on the Racial Attitudes of Blue-Collar Whites Over the Past Few Decades?

Quick question: do we have any good longitudinal data on the racial attitudes of white, working-class men? Maybe something from the GSS?

Obviously this is related to Donald Trump. The question is this: if we assume that Trump is trying to appeal to racial animus among the white working class—a pretty reasonable assumption—this obviously runs the danger of putting off members of other demographic groups. But what about the white working class itself? Is this strategy likely to work even among them? Or is he appealing to a sentiment that’s slowly but steadily fading away?

Can anyone help with this?
