Today it is obvious that the white enclaves are struggling mightily to hold on to power. The 30 – 50 safe gerry-mandered Congressional Districts are white and conservative. No matter how crazy their Rep in Congress is s/he will get re-elected, unless s/he is not crazy enough.
But, let me toss this out from Salon:
When Democratic pollster Stanley Greenberg studied the voters of Macomb County, a hotbed of so-called Reagan Democrats – the county gave two-thirds of its votes to John F. Kennedy in 1960, and the same proportion to Ronald Reagan in 1980 — he found that they no longer saw Democrats as working-class champions. “Blacks constitute the explanation for their vulnerability and for almost everything that has gone wrong in their lives,” and they saw government “as a black domain where whites cannot expect reasonable treatment,” Greenberg wrote.
I was not old enough to vote for JFK and was smart enough not to vote for Reagan. I was born in 1941 and have always seen Democrats as champions of the working class, the poor, the down-trodden. And there are a hell of a lot more poor and down-trodden white folk than there are people of color.
