I just got a smack on the hand for posting a picture of the woman who some may hope becomes first "lady". Fair enough - it was a bit risque.
The term "lady" is a term of respect for a woman, the same way that "gentleman" is a term of respect for a man.
I have no respect for her at all, and wouldn't refer to her as a "lady" any more than I'd refer to Trump as a "gentleman". Firstly she's supporting a man who regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims ― 1.6 billion members of an entire religion ― from entering the U.S.
Secondly it appears that she plagiarised the first lady's speech.
Thirdly it appears that she's lied that she's got a degree in architecture, when she hasn't, whatever her other talents may be.
