How can Indiana not be in the Midwest if you have Michigan in there?

Mittens are now on sale in the local Walmart, all over the Midwest!! If they're in your local Walmart, you're in the Midwest!!!

Well I just happened to be in the local Terre Haute, Indiana Meijer store last night and they already had the mittens and gloves on display, so I guess this means Indiana is in the Midwest.
