The full middle name may be part of the Real ID stuff that the states are being forced to comply with. I suspect my next driver's license will be required to have a full middle name.
My wife always had her full middle (actually maiden) name on her driver's licenses ever since we were married 36 years ago in Missouri. They usually only put the middle initial on them but she got a judge acquaintance of ours to call the license bureau and convince them they could use a full middle name. It remained that way when we moved to MI and later to OH. I don't know if her CHL had the middle name or not, I never asked and I don't think I have it around anymore to check.
