The service that hosts the accounts of all branches of the US military, all major weapons contractors, all three letter agencies, and many foreign militaries, governments, and world leaders guilty of all manner of war crimes, and this is where they draw the line for violence. Really interesting.
The president is the most visible face of the government. Of all the ones you mentioned, it's the only one people actually vote for. What he says and does has the most impact. So I don't find it "interesting", I find it entirely reasonable.
People in the United States do not vote for a president. They vote for an elector who in turn will vote for the president. This is an important and often left out detail in how the American political system works, in theory it could have protected us from the current dumpster fire.
My ballot has the candidate’s name on it, not some elector. If electors conspired to change the outcome, the people would rightfully consider it nothing more than a coup, regardless of the 18th-century design of the electoral college.
