(AP) — Louisiana’s revenue estimates have plunged by more than $2 billion over two years. The state’s income forecasting panel received updated revenue figures Wednesday that showed the state’s general fund dropped an estimated $812 million from the 2007-08 year to last year. And projections of another $1.3 billion general fund decline were built into the budget for this year, the 2009-10 fiscal year. If those estimates hold, that would mean the state’s income has fallen $2.1 billion from the budget year that ended June 30, 2008, to the fiscal year that ends June 30, 2010.
