In response to requests for comment and its latest 990 form, somebody from the group responded via the group's email account without identifying him or herself. The person agreed to send the 990 form via mail, as required by law, but did not respond to any further questions.

It is clear that the coalition's money comes largely from the same sources that are funding the other big conservative groups in the state. Nearly half of the $927,000 it raised in 2011 came from the Club for Growth, which gave it $425,000. In 2011-2012 it also received $150,000 from the Homeowners Alliance and in 2010 it received $25,000 from the Wisconsin Insurance Alliance.
