How Red or Blue is your American English accent?

Fascinating article about how regional accents can be influenced by the political preferences of people living in that region:

"Labov points out that the residents of the Inland North have long-standing differences with their neighbors to the south, who speak what’s known as the Midland dialect. The two groups originated from distinct groups of settlers; the Inland Northerners migrated west from New England, while the Midlanders originated in Pennsylvania via the Appalachian region. Historically, the two settlement streams typically found themselves with sharply diverging political views and voting habits, with the northerners aligning much more closely with agenerally being more liberal ideology.

Labov suggests that it’s these deep-seated political disagreements that create an invisible borderline barring the encroachment of Northern Cities Vowels. When he looked at the relationship between voting patterns by county over the last three Presidential elections and the degree to which speakers in these counties shifted their vowels, he found a tight correlation between the two."

The writer goes on to discuss how politicians have leveraged accents, such as George W. Bush's {fake} Texas accent and Barack Obama's {fake} Chicago accent.
