I did one a while back with myself as President, now let's try a hypothetical cabinet for an alternate universe where Hillary won in 2016:
President: Hillary Clinton (D-AR/NY/IL)
Vice President: Tim Kaine (D-VA)
Secretary of State: Joe Biden (D-DE)
Secretary of Defense: William McRaven (I-NC)
Secretary of the Treasury: Richard Cordray (D-OH)
Attorney General: Loretta Lynch (D-NY)-Holdover from Obama Administration
Secretary of Agriculture: Kathleen Sebelius (D-KS)
Secretary of Commerce: Michael Bloomberg (I-NY)
Secretary of Energy: Julian Castro (D-TX) Technically a holdover from the Obama Administration, but he's changing Cabinet Departments here.
Secretary of Education: Randi Weingarten (D-NY)
Secretary of Health and Human Services: Peter Shumlin (D-VT)
Secretary of Housing and Urban Development: Andrew Cuomo (D-NY)
Secretary of Homeland Security: William "Bill" Bratton (D-MA)
Secretary of Labor: Bob Casey Jr. (D-PA)
Secretary of Transportation: Rick Scott (R-FL) (I doubt he'd accept...but Florida does have that toll road system, so he'd be a clever appointment, if it could gotten by what would presumably be a Democratic Senate)
Secretary of Veteran's Affairs: Tulsi Gabbard (D-HI)
Ambassador, United Nations: John Huntsman (R-UT)
Director, Office of Management and Budget: John Yarmuth (D-KY)
Director, CIA: John O. Brennan (
-NJ) Holdover from Obama Administration
EPA Administrator: Al Gore: (D-TN) (I don't actually think Gore would accept, I just think he'd be Clinton's first choice, given his climate crusade)
Administrator, Small Business Administration: Mark Zuckerberg (D-CA)
Director of National Intelligence: Susan Rice (D-Washington D.C) Holdover from Obama Administration
