For example, John Glenn, Marine Ace Pilot, Astronaut, and Democrat U.S. Senator (Whose leftist policies I hated as Senator BTW), never had his wife speak in public,. She has a severe stutter and is horribly embarrassed by public appearances.
It is a very recent, and mostly Democrat, phenomenon that a candidates wife makes many speeches during an election.
“Also, We do not expect to hear from Mrs. Cain. She may have an issue with public speaking.”
Public speaking ranks as the #1 fear listed by people.
