Someone who dislikes the Washington DC political elites and whose main concern is the economy. Voted for DC outsider Clinton in 1992 during an economic slowdown and GOP fatigue; then for Perot in 1996 as Dole wasn't an alternative to Clinton since he has been even longer in DC. In 2000, he thought Gore was too much of a DC-elitist, not that business friendly and too liberal in general.
Possibly a white male in his late 40s/early 50s at the time and a small business owner from New England with moderate views on cultural issues.
Sounds about right.
