re: Not really.
Bush isn't the only one to mangle "nuclear", and the "h" in "vehicle" is so common now it's probably been accepted in the dictionaries as new usage. It's part of the new dialect I call "copspeak". Police don't answer a call anymore, they "respond to an incident". "Isreal" can be explained, many people pronounce it that way so it's only natural they'd spell it like that. But "Democrat Party" just started popping up a few years ago, first from Republican Congressmen, then commentators, now the rank and file. The opposition can't say "Republic Party" because it would make no sense. I guess the language just evolves.
