From the National Council of Nonprofits:
"A charitable nonprofit may 'not participate in, or intervene in (including the publishing or distributing of statements), any political campaign on behalf of (or in opposition to) any candidate for public office.'
Our society is better today because charitable nonprofit organizations operate as safe havens from the caustic partisanship that is bedeviling our country, places where people can come together to solve community problems. Repeal or revision of the law would damage the integrity and effectiveness of all charitable nonprofits and foundations."
