one speculation I have is that is tied into the common thread of other misspellings. For example Corney for Comey and Obarna for Obama. Supposedly when files get scanned from hard copies to digital if you use certain fonts, specific characters can be incorrectly identified like rn = m. There have been rumors going around that this was used as a loophole to skirt FOIA inquiries. Like searching Comey wont turn up the files where his name got spelled Corney. Maybe calling it Cranton instead of Clinton is like announcing to these fraudsters that their trick of misspellings to hide things from FOIA has been found.
