Governor Scott Walker’s office says there is no reason to take the year’s most controversial item out of the state budget. G-O-P finance chairs John Nygren and Alberta Darling said Thursday it might be a good idea to make funding for highways a separate bill. Nygren says there are some big budget items that Republicans in both houses agree upon, like millions more for public schools — and he says the Joint Finance Committee can work out those matters and see where the political winds blow on transportation at that time. The G-O-P’s divide on road funding got deeper last week, when Assembly Republicans got behind a plan to raise tax revenues on gas while phasing in a big reduction of income taxes. Walker and Senate G-O-P leader Scott Fitzgerald both came out against the plan — and the governor still opposes any gas tax hike while Fitzgerald favors tolls and borrowing to bring in money for new and improved roads.
