Actually voter turnout was 53% of registered voters, of whom 42% voted for Trump.  That means that 22% of registered voters voted for Trump. That's a long way short of half.  But the reality is that all of us, children, women, and men, at "on board" this "ship of state", most, obviously, less than willingly. Don't worry? I would guess that 20 million people about to lose their health insurance are worried. Those of us with investments might worry about a trade war.
Presidents employ speech writers. Didn't you know that? It was a great speech. I can't wait for Trump's next foray into communicating in the English language!
