Impeachment is only for behavior while in office. As much as I dislike Northam, he did not violate law while in office. His support for infanticide could be considered an ethics violation and he should be investigated for that. But a photo from 30 years past is not an impeachable offence, unless the accused is Republican.
I agree, Northam did nothing “illegal”, so I can’t see where impeachment would be an option. Knowing that impeachment is on shaky legal ground, the Dems will continue to howl for him to resign. If Northam is a real cool cucumber, could he, would he stay and fight ?
