Your ideology could influence your speaking style:
Not everyone feels that politics are a part of their core identity. But I suspect that political ideology may become an anchor for accents to the extent that large social groups collectively identify themselves by their political beliefs. According to Bill Bishop, author of The Big Sort, this is happening more and more as Americans voluntarily cluster themselves into homogenous, politically like-minded communities. So perhaps it’s not surprising that George W. Bush acquired a distinct Texan accent, despite having abundant exposure to people from the Northeast, or why Barack Obama sprouted a mild set of Chicago vowels, even though he was fully an adult before ever living there.
