Issues swirling around the Michigan primary

"The Michigan Supreme Court ruled 4-3 Wednesday that the Jan. 15 presidential primary could go forward. A look at some of the issues swirling around the primary:

The Michigan Republican and Democratic parties say holding a primary will encourage millions of voters to go to the polls, increasing voter participation far above what it would be if the parties picked their political favorites through caucuses or party conventions.

Supporters of the Jan. 15 primary such as Michigan Democrats Debbie Dingell and U.S. Sen. Carl Levin say the presidential candidates will have to pay far more attention to Michigan issues since the state will hold its election just after Iowa, Wyoming and New Hampshire. Backers say that could help the state's troubled economy as candidates spend money on rallies and advertising."
