The president is not the boss of citizens the way a CEO is employees at her firm. If that's your view of american civics, time to update your civics lessons.

>Yeah I never understood this either. Does that mean a bachelor US president can't date a US citizen?

Is the difference in power between a US president and the given citizen larger than the difference in power between a 18 and 15 year old? If so, and if relationships should be banned based on power differences, then it seems the only logical conclusion is such a relationship should be banned.

Then again, our laws and social morals are rarely so consistent.

>That doesn't make it wrong to own a knife.

There exist a subset of people in the UK (and in other places but the a subset of the UK subset is particularly vocal and influential) who believe the opposite with varying degrees of passion and with various exceptions carved out.

Edit: Pun not intended but I like it so I'm keeping it there.
