Being curious:
Ted Cruz - BA Public Policy, Princeton; JD, Harvard, magna cum laude
Donald Trump - Bachelors degree in Economics, UPenn;
Marco Rubio - BA Political Science, UFlorida; JD, UMiami, magna cum laude
Ben Carson - Bachelors degree in Psychology, Yale; MD, UMich
In real life: Carson was Director of Pediatric Neurosurgery at Johns Hopkins; Rubio was concurrently a practicing lawyer and served in public office; Trump, real estate (Duh!); Cruz practiced law privately, then for the USAG and TAG, then privately, before being elected US Senator for TX.
In real life:
The CHILL practiced law briefly, had brief and spectacular success in commodities, was enabler-defender of a rapist-philanderer, was elected carpet-bagger Senator for NY, and then was one of the worst, least successful SecStates in US history; Bernie was unsuccessful in life until he became mayor of Burlington, VT and has been in elective politics ever since.
I know, I was too nice to The CHILL and the bern ... what can I say ... I'm a too nice guy,
