Ahhh yes but President Trump was. And I think that's what esimms86 was picking up on. The Pres's tweet offered congratulations & mentined the KC Chiefs & "the great state of Kansas." Former MO Gov Claire McCaskill was the 1st to reply with, ahem, a correction. The original tweet was quickly changed.
Edit: And it is confusing. We have the big one Kansas City MO, then Kansas City KS, and north of the river is North Kansas City MO. Yes each one is their own municipality with individual mayors, etc. I don't live in any of those but of I said I live in the suburb of Roeland Park KS that doesn't do any good. So I alweays say I just live in the "Kansas City area".
