From an post by Jeramey Jannene on Urban Milwaukee:

When the budget finally made it to his desk, Wisconsin Governor Jim Doyle used his extensive veto powers in a lot of ways. The most significant of which was arguably the line-item veto of the Milwaukee Transit Authority and the proposed 0.65% sales tax increase for Milwaukee County. Doyle did not veto SERTA, the authority which is to run the KRM commuter rail line, and the $18 rental car tax. This veto puts back on the drawing board Doyle’s proposal for a three-county sales tax to fund the KRM and bus service in Kenosha, Racine, and Milwaukee Counties, while at the same time not delaying the KRM development process.

The move, which many see as a slam of Milwaukee by Doyle, arguably shouldn’t be completely viewed that way. Doyle did propose a three-county sales tax of up to 0.5% for Milwaukee, Racine, and Kenosha Counties to establish an authority that would operate all of the transit in the area including the KRM. Doyle’s reasoning for the veto was that the MTA didn’t have a regional approach.
