"Why Democrats Can’t Win Over White Working-Class Voters"

This is a pretty good Slate article, though I could have done without the accusations that people who prefer Bill Clinton's welfare reform to the previously open-ended welfare are "racist."

Also, this part of the article doesn't make sense:

in the 2012 presidential election, Republican nominee Mitt Romney ran a series of ads—concentrated in the white working-class areas of Ohio and Pennsylvania—attacking President Obama for “gutting welfare” and “cutting checks” to people who wouldn’t work.

According to that link, Romney ran ads attacking Obama for "gutting welfare reform" — not "gutting welfare," but expanding welfare.
