Although there seems to be no conclusive study that indicates a blight-infected potato is harmful to eat, there was an investigation a few decades back that raised the question of whether blighted potatoes were linked with certain birth defects and therefore expecting moms should avoid them; however, this theory is still inconclusive. Even if there were no risk from blight, however, there is a chance that a blighted potato may also contain other diseases that might indeed be harmful, so it might be best to just throw the entire potato away. (And, no one should eat a green potato.)
If you want to take a chance with the tubers from your blighted plants, then check to see if the potato itself looks healthy. If it does, it likely would be OK to eat. If there is any sign of corky dry areas, scabs, etc., on the tuber, then you can cut that part out and eat the rest, or just throw the whole potato out. If there is any slime or mold, throw the potato out. If it has an odd flavor, also throw it out.
If your potato tubers show any sign of disease, do not use them for canning--even the good parts.
