Now, I see in Chris Sullentrop's report in Slate, that Kerry actually did mispronounce brat:
Here in Sheboygan, during a "Kerry-Edwards '04 Brat Fry," Kerry adds to the litany [of regional mistakes] Friday by referring to the local food as a short-A "brat," the way you would refer to a spoiled child. "Brot!" yell members of the crowd. For good measure, Kerry makes the mistake at the end of his speech, too. "Before I get a chance to have some braaats ..." "Brots!!" some women near me shout in frustration.For crying out loud! How inept do your people have to be, when taking you to a brat fry not to tell you "remember it's brot"? You know, I wouldn't mind if the candidates didn't do any of this traveling around to colorful, small-town events. I'd rather see Kerry sit across the table from Tim Russert on "Meet the Press." But, good Lord, if you're going to use the hokey Americana method of campaigning, the whole point is to look as though you belong there when you're there.
UPDATE: An emailer quips: "So you're telling us that Kerry's staff failed to prepare him for the wurst?"
