I think is  a much larger base for Trump in particular.   I don't think it's the base of the 'other' Republican party.      It's clearly a part of both.   

Many (most?) white men are not concerned about getting a 'raw deal', nor do we carry a sense of victimhood.  But that group absolutely exist in American culture, including Eugene.

*Hmm, and is this the 'forgotten America' that Dems want to bring back into the fold?   (at least some do).

Problem is that most of us are a mixed bag of good and bad, depending on who you ask.   I've always found racism particularly vile.  But the more suttle unconscious  bias of a narrow life experience, is an insidious obstacle to racial equality and that can be found among liberals as well.  (Easy to be liberal in a 95% white community).    

Rest assured, there is a lot of good people working to defeat racial discrimination.   Those should be the folks in the headlines, not just the angry mob.   But we know which type 'sells'.
