Ford CEO, Chamber spokeswoman support Democrats' business tax plan

Here's an item from the Detroit Regional Chamber's Mackinac Policy Conference on Mackinac Island:

Blue and white stickers proclaiming "Pass the MBT" began appearing on lapels Thursday afternoon, about the same time that Senate Majority Leader Mike Bishop, R-Rochester, told reporters that the House's Michigan Business Tax plan needed work.

Democrats like the House plan because it's a better deal for manufacturers, especially carmakers. Republicans prefer a plan that offers more incentive for small businesses.

Ford said the Democratic plan would create a more competitive tax structure for Michigan manufacturers, shift more of the tax burden to out-of-state companies that do business in Michigan and encourage research and development in the state.

The Detroit Regional Chamber, which helped write the House plan, weighed in to support it. "We really feel the House approach is better," said Sarah Hubbard, spokeswoman for the chamber.

If the GOP was truly the 'pro-business party,' then why are business leaders flocking to the Democratic plan instead?
