Paul Levy has written a characteristically thoughtful response to my suggestion that he should have disclosed his support for Republican gubernatorial candidate Charlie Baker when he criticized Gov. Deval Patrick’s proposal to control rising health-care costs. We also discussed it in the comments.
Levy offers a spectrum, and I’d answer it this way: If someone is writing a public blog offering commentary on political issues, then yes, he should disclose if he has publicly endorsed or donated money to a candidate. But no, there’s no need to disclose your private voting intentions, even if you have told friends. The former makes you a supporter; the latter merely makes you a likely voter.
Levy is not a journalist, but he’s doing journalism of a sort. Thus, not all of the ethical rules that journalists have to follow apply to him (it would be anathema even for an opinion journalist to give money to a candidate, for instance). But for someone in his position, it’s better to disclose.
Final point: Of course, Levy had already disclosed his support for Baker. It’s not a matter of being open; he is. It’s a matter of informing those who might not be aware of his political activities.
