I think that many regional accents are getting muted, due to the homogenization from television, and the much greater amount of intermixing as people move to different areas. The article doesn’t really explain the difference in the coffee pronunciation, though. I say “cawfee,” as she spells it. A New Yawkah says “kooawfee.”
I share it, but I suspect we’re going to be disappointed. I don’t know what the filing deadlines are for the upcoming primaries, or how many delegates he’d realistically be able to get.
