If a minister stands up in his own pulpit and endorses a candidate, and the only people who can hear him are those sitting in the pews, I'd say, fine, that ought to be allowed: it's protected free speech.

However, if the church happens to own a radio or TV station, and they use it to broadcast his sermons, I'd say that's going too far.

There ought to be a place somewhere in between to draw a line, although I haven't quite figured out where it is.

Whatever rule is adopted, it ought to apply to liberal and conservative churches alike.

That's my own opinion about what the law ought to say; it's not an interpretation of what the law now says.
