He contacted the maintainer of the selectric composer website and had him try and reproduce the memos using it because so much of the left is in a tizzy over this machine. The guy talks about how hard it is to center text while using a proportional font because you have to know EXACTLY what spacing is in each letter. But the header would be something that Killian would have to type a lot and it was THEORETICALLY possible that he figured it out and just always used that same spacing. Or even that he did it perfect once (not just perfect to the eye, perfect to the level of mircosoft) and just xeroxed it and used it over and over. But if it is still perfectly centered even with the superscript th that is going to remove a couple more of the left talking points. I already emailed him a couple minutes ago on this one.
