I can't argue with the validity of that but at least Reagan publicly endorsed the benefits of a traditional family life and acted as "something" of a role model for that in his second marriage with Nancy. GWB and his father have done the same.
It is one thing for a politician to talk the talk on *any* subject but few of them walk the talk in their own personal lives. I think a politician who does what he says others should do, should at least get credit for doing that much.
