Governor Scott Walker and Senate G-O-P leader Scott Fitzgerald are not saying much about a major tax overhaul that’s being worked on by Brookfield Assembly Republican Dale Kooyenga. Media reports say he would apply the state’s five-percent sales tax to gasoline, cut the current gas tax by up to a nickel, reduce borrowing for new highways, move toward a flat four-percent income tax, end the state’s minimum markup law for gasoline, lay off 180 D-O-T engineers, and repeal prevailing minimum wage requirements for road and bridge work. Fitzgerald says his G-O-P caucus is looking at a narrower option to use general tax revenues for highway work. Walker says Kooyenga’s plan is still being worked on, and he wants to see the entire package before commenting. Assembly Democratic Minority Leader Peter Barca calls it a “complete non starter.”
