Some of the most powerful corporations in Michigan are hoping you don’t hear about this new ballot proposal. It’s called Mop Up Michigan, and it aims to ban political donations from the state’s biggest utility companies like DTE and Consumers Energy, along with other big corporations that are making huge money off government contracts.

And if it makes its way to the ballot next year, Michigan voters—not lawmakers—would get to decide whether those companies should still be allowed to bankroll Michigan politics.

Here’s the deal:

Mop Up Michigan stands for Michiganders for Money Out of Politics. Organizers want this proposal on the ballot. And to get there, they need to collect about 357,000 signatures from registered voters within a 180-day period.

Folks with clipboards are on the streets now, so that clock is ticking.
