Wolverine in southern Iowa?

Residents of a nursing home in southern Iowa received a visit from a bedraggled animal recently, and my hometown newspaper published a photo of the critter with a headline that posed the question of whether this was a wolverine? Local wildlife experts expressed doubts of the wolverine identification, but also expressed uncertainty as to its actual identification.

I posted the photo on my facebook page and asked my colleagues to comment. As of today, most agreement seems to be that this is a very wet, probably very upset woodchuck. The white markings on the nose and behind the chin make me agree. What do you think?
