State economists on Monday found millions of extra dollars for the state’s public schools, but also a $29 million shortfall in takings from tobacco taxes and a landmark legal settlement with the tobacco companies. The Revenue Estimating Conference projected that $128.4 million would remain unspent at the end of this fiscal year within the Educational Enhancement Trust Fund and the State School Trust Fund, financed primarily through Florida Lottery proceeds, slot machine taxes in South Florida, and proceeds from the sale of unclaimed property.
