On its face, a corporate political contribution looks simple. Like this little one from Minnesota's biggest company, UnitedHealth Group.
UnitedHealth Group gave $10,000 to Rely on Your Beliefs, a political action committee that gives exclusively to Republicans. Rely on Your Beliefs then gave $50,000 to the Senate Leadership Fund.
The Senate fund, a Republican super PAC, then spent more than $18.5 million on attack ads this month opposing Cal Cunningham, the Democratic candidate for U.S. Senate in North Carolina.
UnitedHealth may not have intended to fund negative advertising in what has become the most expensive Senate race in U.S. history, but it is now linked to those ads through the winding and often murky money trail funding the 2020 U.S. elections.
"UnitedHealth Group works with a wide range of policymakers who share our commitment to building a next-generation health care system," company spokesman Eric Hausman said last week. He declined to talk about its specific political donations.
In the face of broad social movements and controversies, Minnesota's biggest companies and others around the nation are beginning to make more measurable public commitments to the environment, racial equity and worker well-being.
Businesses tout such efforts publicly in news announcements, even commercials, and respond to activist stockholders who eagerly test actions against words.
But gaps still remain between the values companies publicly espouse and how they spend their money on political campaigns. Part of the reason for that is because so much corporate giving is funneled through third-party groups that shield the businesses from direct accountability.
