Walker's billionaire backer's business pays no state income tax

Diane Hendricks, who became known this week as the $500,000 donor with whom Scott Walker shared his "divide and conquer" plan, is worth $2.8-billion. 

Her Rock County company, ABC Supply , paid exactly $0.00 in state corporate income tax in 2005, 2006, 2007 and 2008, the latest years available, according to the state Dept. of Revenue. 

And her main concern is making Wisconsin a right-to-work state?

Why are we not surprised?
