NJ grassroots anti-tax activists have already begun distributing bumper stickers around the state, and charge that the Whitman Administration has sold out its pledges of fiscal conservatism. Business and labor groups, on the other hand, are launching a media campaign underscoring the need for infrastructure investment. The NJ Legislature will likely vote next week on whether to put the tax hike on November's ballot. The Tri-State Campaign would back the hike if the Governor would agree to appropriate controls on how the revenue would be used, but the administration refuses to consider the idea. The Campaign fears NJDOT's sprawl-causing road construction activities will accelerate once the tax hike expands the agency's budget.
