Louisiana's lawmakers have spent months combing through the $6.8 billion in tax breaks on the state's books with an eye toward getting rid of those deemed unworthy of the spending. If they can settle on a list of what's poor-performing, state leaders are at odds over what to do with the savings. A struggle is brewing over whether the dollars raised by eliminating a credit or exemption should be used to plug budget holes or to create new tax breaks. Some lawmakers see an opportunity to offset cuts in a state that has been hit with repeated rounds of budget slashing and that faces a $963 million budget shortfall next year. Gov. Bobby Jindal disagrees, saying any savings from removing a tax break should pay for lowering taxes somewhere else.
