Colorado schools districts are asking voters for more than $1 billion in tax increases in Tuesday’s election, and campaign committees supporting those proposals have raised some $1.25 million to persuade citizens to vote yes.

Election 2012 LogoDenver Public Schools is requesting about half of the statewide total, a $466 million bond issue and a $49 million in operating revenue.

Similarly, the $555,187 raised by Together for Denver’s Schools, the campaign committee backing measures 3A and 3B, is nearly half the total raised by campaign committees statewide.

The Denver committee has tapped a long list of deep-pocketed corporate and individual donors from Colorado and around the country, including New York City Mayor Michael Bloomberg. He contributed $75,000 to the effort, according to campaign finance reports filed Friday with the secretary of state’s office and covering activity from Oct. 12 through Oct. 28.

In comparison, the opposition committee, No on Denver 3B Bond, has raised pocket change – $1,890.

Some $1.04 million has been raised for tax election campaigns in four major metro-area districts, including Aurora, Cherry Creek and Jefferson County plus Denver.

Citizens for Cherry Creek Schools, which is campaigning for a $125 million bond issue and a $25 million operating increase in that district, raised an additional $50,966 during the most recent reporting period. Recent fundraising by Aurora Citizens for Excellent Schools and Citizens for Jeffco Schools was more modest.

While the total raised in Denver may raise eyebrows, when calculated on a per-student basis it lags behind the campaign cash raised in two smaller districts that are seeking bond issues to raise matching funds for state construction grants.

In the Lake County district in the central mountains, with 1,224 students, Citizens for Lake County Schools has raised $11,671, or $9.53 per student.

The Montezuma-Cortez district in the Four Corners region has 2,431 students, and the Cortez 21C High School Committee has raised $18,736, or $7.70 per pupil.

DPS has 80,890 students, so the $555,187 raised by the Together committee amounts to only $6.86 a kid.

There are distinct and traditional patterns in giving to district campaign committees. Large and some medium-sized districts draw funds from construction companies, home builders, architects, teachers unions, bond companies and other businesses, as well as from a long list of individuals. Committees in smaller districts receive contributions from a few individuals and local businesses, and some rely on fundraisers like pancake suppers, barbeques and auctions.

On the spending side, most of the money in all districts is concentrated on low-tech measures like mailings and yard signs, plus newspaper and some radio advertising.
