From Education to HUD, from Transport to the EPA, there isn’t a single person Trump has chosen that isn’t uniquely unqualified for the job ...
SecEd DeVos has been involved in education for decades, just for schools and methodologies of which Proggies knee-jerkingly hate (under union tutelage). She also has a degree in business economics and grew up in and married into families of entrepreneurs.
SecHUD Carson, besides being a leading neurosurgeon at Johns Hopkins was also the hospital's Director of pediatric Neurosurgery for 19 years (i.e. administrative). His experience in public housing was during his childhood.
SecTrans Chao has a BA in Economics and an MBA from Harvard. For several years she worked in banking, with an international focus. And then she worked in the Transportation Department under Reagan and GHWB and was Chair of the Federal Maritime Commission. She was President and CEO of United Way during 4 of Clinton's years, and then was SecLabor for all 8 years of GWB's Administration. During Obama's years she served on various corporate and non-profits' boards, among other things. She shines a glaring spotlight on NanceGreggs' ignorance.
SecInt Bernhardt has a law degree and has practiced law. He worked in several roles in Interior in the second half of GWB's second term. He returned to law practice, representing what Proggies would consider the "wrong" sort of clients (including San Joaquin Valley farmers trying to get back their water). He's highly qualified, just in ways Proggies hate.
