Prior to 2021, when was the last New Jersey gubernatorial election where a Democrat did better in Somerset County than the state as a whole?

In the 2021 New Jersey governor election, Phil Murphy, a Democrat and the incumbent, won 51.5% of the vote statewide. However he won 51.7% of the vote in Somerset County a suburban county which has swung heavily to Democrats from 2012 to 2020 like many suburbs. Based on my reading of historical data, the Democrat getting a higher percentage of the total vote in Somerset County than statewide average is unprecedented in recent history. When was the last governor election where the percentage of the vote for the Democrat (including 3rd parties) was greater in Somerset County than statewide (if it ever happened)?
