LOL.
There is no such thing as a Missourah accent. Everybody knows that the citizens of the Midwest are the only Americans that have no accent.
Gephardt has a Missouri rather than a Missourah accent. He's from St Louis. Both cannot be "correct."
Well Whatever he has it sure sounds peculiar. Rush makes fun of him all the time when he says Warshington or Congriss. It might be a touch of Chicagoan. People insist that Terry Mcawful has a Midwestern accent,but it sounds strictly central New York to me,and it sounds nasal and icky just like where I came from. It takes on a really off-putting sound when Mcawfull opens his mouth to spew his hatred and lies with venom so sharp it makes your ears hurt.
Maybe not, but there is a definite St. Louis one with flat, nasel vowels and consonants in the throat. And the letter combination "or" is pronounced "ahr", hence why we always sound like we're praying to animal fat.
