The proposal to lease Memorial Health System to University of Colorado Health enjoys strong backing from the city’s voters, according to a new poll commissioned by the “Great City, Great Care” committee backing the lease measure.

According to Colorado Springs Mayor Steve Bach, who supports the lease and revealed the results at a rally Monday morning, the poll found 67 percent of likely voters are in favor of the lease, 11 percent are opposed and 21 percent are undecided.

“Once maybe in a generation, our city has an opportunity to make a quantum leap forward,” Bach said. “This is one of those moments.”

The telephone poll of 600 likely voters was conducted by the firm Hill Research Consultants last week. Stephannie Finley, who heads the “Great City, Great Care” group, said she was heartened by the strong support, but added that the group isn’t taking anyone’s vote for granted.

“We want to earn the 21 percent” that’s undecided, Finley said. “We want to go big.”

“Great City, Great Care” plans to begin airing TV commercials this week, to coincide with ballots for the special election going in the mail. The ballots must be returned by 7 p.m. Aug. 28 and the Memorial lease is the only question on the ballot.

“Great City, Great Care” is receiving most of its support from Poudre Valley Health System, which partnered with University of Colorado Hospital to create University of Colorado Health last year.
