An overview of MI PACs’ financial activity is available at CNNMoneyline.

A relatively light election schedule, and possibly Michigan’s sluggish economy, are slowing the amount of money flowing into the state’s political campaigns.

The state’s 150 largest political action committees had raised a combined $27.3 million for the 2008 election cycle through July 20, according to a report released Tuesday by the nonpartisan Michigan Campaign Finance Network. That’s down about 9 percent from what the state’s largest 150 PACs had raised through mid-July 2006. Some of the PACs on the list for 2008 are different from the list for 2006.
