In response to your question, yes, I checked Kerry's fonts on his DD214 and found TWO different fonts on this one supposedly typed document...

There's nothing unusual about that. I'm fairly certain you'd find the same variations on Bush's.
i think i know why the 2 different fonts in the dd214... i wonder if Kerry himself, did his own Name and date of birth and such and someone else did the rest.. or maybe a secretary in a different office did the personal data and someone else did the other data...
