It's just a PR move to make it look like Democrats care about poor families. It's not the price of diapers, but the amount a family earns that should matter. If the minimum wage were higher than it wouldn't even be an issue.
If anything it's a good way to get gamers to go over to Lays or Pringles. WTF were they thinking making fun of a demographic that is practically a cornerstone of their consumer base?
I remember a story where a police officer has to go into a mental institution to either inspect it or look for her partner. She ends up diapered and has her head shaved.
