It is abundantly clear that Donald Trump does not understand that he cannot fire Angela Merkel (if she needs to use the bathroom), Vladimir Putin if he is "unfair" like CNN, or dismiss any members of congress who he thinks are "the dumbest person(s) he's ever met."
It is also clear that Mr Trump does not understand that presidents -while powerful- can not insult their way out of being ignorant about something they legitimately do not understand.
We petition President Obama to publicly instruct Presidential hopeful (though we hope not), Donald Trump on these simple matters of fact so that he does not become president and then get upset and bomb someone in his rage.
