In 2004, the Democratic governor of Iowa, Tom Vilsack, was officially neutral in his party’s primary. But neither he, nor his wife, Christie Vilsack, saw anything wrong with the first lady of the state making an endorsement, and it helped Kerry a great deal when he needed a spark:

Many saw–and were intended to see–Christie Vilsack’s endorsement as the shadow endorsement of Tom Vilsack. “We talked about it beforehand,” he said. “I mean, obviously she isn’t going to do something that–you know, her first loyalty is, obviously, is to me–and she wouldn’t do anything or want to do anything that would be hurtful and harmful to me. And if I had said, ‘Gee honey, an endorsement’s not really a good thing,’ I’m sure that she would have given very serious consideration to not endorsing him.” But Vilsack didn’t say that.

I mention this because New Hampshire Democratic governor John Lynch is officially neutral, but his wife Susan Lynch just endorsed Hillary.

Much like with the Vilsacks, I’m sure John Lynch could have said, “gee, honey, an endorsement’s not really a good thing.”
