Elon Musk is not running for governor of NJ, so viewing it as "a trend of corruption in his opponent's administration" is not advisable.
The other problem with this is that the Gov is still has popular support and Mr. Musk probably negatively influenced those people. Further, making this an actual political fight is really not something Mr. Musk should be looking towards because their is a fair amount of material the Gov can use on Mr. Musk.
Think of every attack that can be levied against the elitism of Silicon Valley and personify it in the person of Elon Musk. It could get quite nasty and the valley doesn't really do well in political games.
