Nine donors gave the group, which registered as an independent expenditure committee in June, a total of $205,000, according to filings submitted to the Secretary of State’s office on Friday. Bloomberg donated $75,000 and Anschutz gave $9,000.

The largest single donor to Great Schools Denver was the advocacy committee of the group Education Reform Now, which is affiliated with Democrats for Education reform and which also has a local committee. The organization contributed $90,000 of Great School Denver’s reported contributions.

Oakwood Homes, which is led by Pat Hamill, and Kent Thiry, chief executive officer of DaVita, each contributed $15,000. And John Fox of MarkWest Energy Partners donated $1,000.

Anschutz, Thiry and Hamill have already donated to individual candidates in the campaign. Friday’s campaign disclosures revealed that Hamill donated a combined $18,000 to southwest Denver candidate Rosemary Rodriguez, central Denver candidate Michael Johnson and northeast Denver candidate Landri Taylor. Anschutz contributed $16,000 in the first campaign finance reporting cycle to those three candidates, plus at-large candidate Barbara O’Brien. Thiry gave the candidates $8,000, while his wife Denise O’Leary contributed $33,000.

And Bloomberg made Colorado headlines earlier in the week when his philanthropy gave more than $1 million to the campaign to pass the education tax measure Amendment 66.

The largest single recipient of the group’s expenditures, which total $161,709 so far, was the political consulting group OnSight Public Affairs. OnSight is also working with the campaign to pass Amendment 66.
