It appears there are no campaign committees formed surrounding the city's ballot measure on the Nov. 1 ballot, but there is a nonprofit that has formed to support the city-owned Memorial Health System.
The website linked above explains the goal of the group like this:
We are a group of concerned Colorado Springs residents committed to Memorial Health System remaining a vital part of our community. For this to happen, Memorial Health System must become a nonprofit entity where all the control and all the money remains local.
The website also contains various reports about the process the city is going through to remove city liability and, hopefully, give Memorial the freedom it needs to be successful in the changing world of health care.
Here's the ballot measure: "Shall Ordinance No. 1854 (1949) that requires City Council to levy a tax to pay for any operating deficit of Memorial Health System be repealed?"
