Who knows if the Bush National Guard documents are forgeries or not. I certainly don’t know.
However, in the mid 70s, we had a ball typewriter at home that had a bunch of different fonts available, including non proportional ones. I hated those fonts, because they made it extremely difficult to correct and go back and erase. I used this typewriter a decade later for college applications, and it became apparant to me that I had to use proportional fonts to be able to exploit the “erase” feature. What’s more is that there were dozens of fonts available for this typewriter. At home we had three. Pica, Elite and something else that wasn’t proportional.
So if some are arguing that the documents are fake because of the fonts, that’s bullshit. Typewriters could do that by the mid 70s, and it’s not hard to find out that government quality typewriters could do this in the 60s.
It might still turn out that the Bush docs are forgeries. The real ones were probably “accidentally” destroyed at some point. But saying they are forgeries based on the font is bullshit. Fonts existed prior to MS Word, and some electric typewriters were pretty damn good.
