I'm 73....and remember her. She never appealed to me and her voice drove me crazy.
I’m certain Melania knows plenty about many First Ladies. You aren’t giving her credit for brushing-up on her job or doing any background research ;-)
The ‘voice’ was something of a cultivated affectation of the time. I’m sure there are many to whom she didn’t appeal, but that doesn’t take away from her accomplishments.
