The US government has been increasingly dysfunctional for several years now. I'd like to remind you that Congress has actually shut down the government's operations on more than one occasion, tried to blackmail the Executive with a government default, has passed a record low number of laws and refused to review Obama's appointment for the vacant SC position. Congress, for practical purposes, went on strike to attempt to ensure that Obama would not be able to accomplish most of his goals - in effect punishing the US people for political purposes.
This isn't getting any better with the change of POTUS - now the Democrats are determined to stalemate the new Executive in any way possible. This isn't healthy, this is destructive, and it's certainly not functional. It's disgraceful!
You're wondering whom I'm calling "borderline mentally challenged?" That would be Donald Trump, about whom many professional psychologists have voiced concerns of mental competency. He hasn't yet given the US public any indication that he's even as smart as George W. Bush or more knowledgeable of world politics than the average 5th grader.
The rest of the team is a mixed bag with regard to competence. Certainly Nancy DeVos has shown no indication of capability for her position, and the rest of the team has definitely been selected for ideological proximity to D. Trump rather than capability. Disturbingly, the EPA appointee is a declared enemy of the EPA, the energy guy is a global warming denier, and the national security guy is someone who has publicly announced his intention to overthrow the state. His pick for AG was previously disqualified for being an outspoken racist. Similar (dis)qualifications apply to numerous other of his picks.
I'd say, au contraire, that a considerable amount of delusion is required to believe that a team this poorly matched to their jobs will be effective improvers of the nation's status.
