You calling Trump a hypocrite? How dare you!!
On a serious note, these things happen all the time in politics. He probably should but so as to apply to the next presidential election. But anyway we've said before it's mostly when things don't go as they're supposed to go that people start bringing up democratic procedures and their flaws. Sour grapes.
Even before the Brexit vote, I was thinking, is 51 % enough of a majority to warrant such a drastic measure as leaving the EU or should it be a increased majority vote, say 60%. But that wouldn't be fair though would it.
