Yeah, that's one of those "data smells" that makes me disregard the entire thing since they don't offer a credible (or any) explanation that explains a 3-way tie.

Reproducing here for reference:

    Florida             $98,670  17.0%
    Hawaii              $98,670  17.0%
    Washington, D.C.    $98,670  20.9%
