Oakland County Executive L. Brooks Patterson introduced this idea in his State of the County Address a few days ago.
if this passed it would cause a 1.85 Billion dollar hole in the 2007 Budget. Legislators would have 10 months to make up the 1.85 billion in loss revenue.

"She will not support any plan that shifts the tax burden from wealthy corporations to Michigan's hard-working men and women,"
also this just moves the repeal date of the Single business tax up to 2007. In 2002 Engler and the republican controlled legislature passed a law repealing it in 2009. So if this fails, the state still has to fix this or will have a 1.8 billion dollar hole in the budget.
I wouldn't underestimate Patterson this could easily be on the ballot, but I doubt it would pass. People against it would just have to call it a tax cut for businesses and it would be finished.
