If you look at the history of the IP (https://en.wikipedia.org/wiki/Special:Contributions/72.79.14...), there are a few other minor edits, here is one:

"Are usually as dumb as brandon's and that is REAL dumb"

This was added to to the Bichon page, the rest of the edits are similarly juvenile

Yeah, regular staffers and congressmen probably don't have the technical skills needed to edit a Wiki page.

No, I think they just lack the inclination and/or are smart enough to create an account or make edits from a different location.

That ip also accessed the fiu digital collections in June: http://digitalcollections.fiu.edu/web_stats/usage_201306.htm...

Entirely possible that there is zero connection to FIU or the state of Florida in general.
