Is the Professional Staff Congress Violating Section 501(c)(3)?

NYPIRG is an ideological advocacy group that encourages college students to advocate on behalf of causes of which Ralph Nader approves. Under Section 501(c)(3) of the Internal Revenue Code, universities receive tax exemption on the condition that they do not engage in political lobbying, engage in ideological advocacy or political activity. I just received the following message through campus e-mail from Scott Dexter, a representative of the City University of New York's faculty union, the Professional Staff Congress. I would guess that this was not authorized by the university. Is this political advocacy? You be the judge.

Subject: Student voter registration with the PSC and NYPIRG

The PSC is urging its members who work in the classroom to invite a representative from NYPIRG (the New York Public Interest Research Group) to their classes to register students to vote. At Brooklyn College, NYPIRG can be reached by email at brooklyn@nypirg.org or by phone at (718) 859-7177; their office is in 0302 James.

The New York deadline for voter registration is Friday, October 10, so please get in touch with NYPIRG soon to arrange visits to your class.
