Supporters and opponents of Colorado’s statewide ballot measures have pumped $41.7 million just this year toward swaying public opinion on issues that could have far-reaching implications if passed in November.

During a presidential election year in which issues such as abortion access hang in the balance, and at a time when many families are struggling to make ends financially, Colorado’s ballot questions are taking on heightened importance. Measures such as a 22-week ban on abortions and having Colorado support the national popular vote for president are receiving attention — and contributions — from across the state and country. With less than a month to go, advocates are making their final pushes to Election Day — including in the money race.

The committee fighting the proposed ban on abortions after 22 weeks has brought in the most contributions of any issue committee at almost $6.5 million in 2019 and 2020, while proponents of Proposition 115 have raised a fraction of that, according to filings with the Colorado Secretary of State’s Office by Tuesday’s deadline. Three committees supporting the measure raised about $369,000.

Opposition to the abortion measure is being led by women’s reproductive rights groups and progressive allies such as ProgressNow Colorado, Colorado Organization for Latina Opportunity and Reproductive Rights, and Cobalt. Supporters of Proposition 115 include Catholic Charities and citizen advocates.

Although Colorado voters have rejected abortion bans three times before at the ballot box, the vote comes at a critical time with the U.S. Supreme Court vacancy left after the death of Justice Ruth Bader Ginsburg. President Donald Trump has nominated conservative Judge Amy Coney Barrett to replace her, leaving advocates worried about the potential of Roe v. Wade getting overturned.

Colorado is one of only seven states that doesn’t have gestational limits on when an abortion can take
