Christian groups couldn’t keep up in campaign fundraising in Colorado’s battle over a ballot issue granting terminally ill patients the ability to request life-ending medication.

Colorado voters overwhelmingly passed the initiative, Proposition 106, last month, with just under 65 percent of the electorate supporting the effort. Voters acted after the legislature failed twice in recent years to advance a similar measure.

Usually considered a financial force not to mess with, church organizations-largely led by Catholics-posted impressive enough numbers on their final campaign-disclosure reports for 2016, filed Thursday. They reported raising more than $2.6 million in contributions.

But the church’s fundraising was eclipsed by proponents, who took in more than $5.3 million.

Yes on Colorado End of Life Options, the group that pushed for passage of Proposition 106, was largely fueled by Compassion and Choices, an organization dedicated to legalizing medical aid-in-dying across the nation. Compassion and Choices contributed more than $4.5 million to the ballot effort in Colorado, according to the disclosures filed Thursday.

To be eligible for a prescription, patients need to be at least 18 years old; have a prognosis of six months or less to live, confirmed by two doctors; be mentally competent; self-administer the medication; and make two oral requests, separated by 15 days, as well as a third written request, signed by at least two witnesses.

Compassion and Choices on Wednesday launched an outreach effort to educate Coloradans and the medical and pharmaceutical communities on the new law. The group is unrolling a bilingual education campaign.

Proponents of the measure outpaced opponents right through the election.

Between Oct. 27 and Nov. 30, Yes on Colorado End of Life Options reported $67,790 in contributions. Opponents, registered as No Assisted Suicide Colorado, raised $29,206 during the same period.

Final fundraising reports for issue committees were filed Thursday in Colorado.
