The Johnson Amendment is at risk again. This Amendment (passed in 1954) forbids nonprofits from endorsing candidates. We can of course take positions on ballot measures and legislation, but the Johnson Amendment protects us from being pressured to support a particular candidate for Congress, Board of Supervisors, or any other elected office.
Imagine if a major donor asked your organization to publicly support his choice for the Board of Supervisors. Or if a foundation president sent a letter to grantees asking them to publicly oppose the same candidate. The Johnson Amendment protects us from this kind of pressure.
