TRENTON, N.J. (AP) — The New Jersey Legislature has authorized a statewide referendum on whether two new casinos should be permitted in the northern part of the state. The state Assembly passed a bill to authorize the referendum by a 54-16 vote yesterday, with three abstentions. Earlier in the day the Senate passed the same bill by a 34-6 vote. The measure does not specify locations. But the most commonly talked about possibilities are East Rutherford and Jersey City. The question will appear before voters on the November general election ballot.
