COLUMBIA, S.C. (AP/WVOC) - A bill praised as the largest overhaul of state government in 20 years is on its way to Governor Nikki Haley's desk.

But explaining how taxpayers benefit won't be easy as she and her Democratic opponent tout its passage on the campaign trail.

The measure won't produce immediate savings, as layoffs are expected. In fact, it will require additional spending initially.

But supporters say the soon-to-be-signed law will eventually save the state millions through centralized purchasing and technology services.

Other benefits are less measurable, with supporters summing up the changes as making government more effective and accountable.

It took the politically odd duo of Haley and Kershaw County State Senator Vincent Sheheen to finally push the idea through ahead of their election rematch this November.
