REALLY? I'd not heard this. Are you certain? Can you provide a link documenting this?
Wow - if your statement is, in fact, true, this is a disgrace. It's simply unconscionable to deliberately disenfranchise those protecting the country.
Does anyone on this board know if other states have similar rules in place - or is Michigan unique in this regard? (Again, assuming MI actually DOES disenfranchise as stated.)
