It depends on what the meaning of "don't" is. When Maureen Dowd asked John Kerry if Dick Cheney's joke about Botox was "a way to mock him for an effeminate vanity," he said:

"No, I don't have it," he says coolly. "Vanity or Boxtox [sic]?" I ask, grimacing. "I don't have Botox, but whatever their game is, I don't care," he replies without a wisp of a wince. "That sort of thing is so childish. In the end, people will care about real choices that affect their lives."

Didn't everyone learn from the Lewinsky incident that when someone answers your question in the present tense, you need a follow-up question about the past tense?

Oh, and since Maureen Dowd had gone in search of info about Botox (and was mostly trying to make him react to something, anything, to see if he could still move his face), didn't Kerry implicitly call Dowd childish? But isn't that really why we read Dowd?
