The Great Lakes states have been much more tolerant of the recovering wolf population than the Western States. It may be cultural and it may also be due to the incredible number of deer in the Great Lakes.
The deer hunt in the Great Lakes, like the deer and elk hunt in West, provides a lot of extra nutrition for wolves as they feed on the gut piles and take down the escaped wounded ungulates.
Nine dead wolves should be put in perspective. I suspect more than that are shot in Idaho than that during hunting season. While some advocate a wolf hunt, in Idaho, Wyoming, and Montana there has been a de facto wolf hunt year round. It is illegal, but its effects should be recognized.
