"Michigan Working Families" identify yourselves

Yesterday I posted a message from a group called "Michigan Working Families", well, friends of mine have recieved two more robocalls from them.
I still can't find any information on them and am very curious to know just who they are and who funds them.

Call 1:
"Another broken promise by Jennifer Granholm. She promised smaller class sizes, instead she cut funding for public education. Class sizes are now bigger under Jennifer Granholm. But breaking a promise isn't all. Granholm opposes proposal five, solutions that could move one billion dollars to the classroom. When you look at the record and beyond the hype, Jennifer Granholm is no friend to our public schools. This message has been brought to you by Michigan Working Families."

Link.

Proposal five would effectively force either a tax increase somewhere, or roughly $500 million in cuts from other departments or services. While we all agree that public education funding is a critical need for helping the state move forward, mandating funding levels without thought to need seems reckless. At least to me.
And by the way, that's rich coming from the family that wants the state to help fund christian education through the voucher system and effectively take money OUT of public schools.
Jackass.

The tone of the second one is downright crude.

"Wow. So first we find out that Granholm makes empty promises to autoworkers, and then today Jennifer Granholm's campaign says on WJR radio that they have no regrets for supporting NAFTA. Frankly I'm pissed at watching another politician lie to us and do nothing to help us. This November I'm voting for a change. I'm firing Granholm and voting for MY job. This message brought to you by Michigan Working Families."

LINK.

Whew. Huh. I wasn't listening to WJR so I have no idea if this was said, what was said or what context it was in, but here's the thing, Governor Granholm has been consistently for enforcing our current treaties in order to make the playing field level for the auto industry.

I ask again: who are you "Michigan Working Families"? Who funds you? Where are you located? Where are you headquarters? Who is on your board? Who is writing your copy? Where are you recording at? Who are you using to robocall, because your number keeps popping up as "caller unknown"?

Someone with more resources than me needs to do some digging, because this smells rotten. I'll keep looking, but i'm just a guy. The more help the better.
