Don't think that makes much REAL difference; Trump said it and is NOW the President of the US.  If I could edit (time has passed so I can't) I would correct the statement to, as you correctly state, to read  "Donald J. Trump, private citizen, and  future President  of the United States of America."  The man is a known sexual predator.  What more proof do you want than his above statement on video/audio tape?  If he's the kind of president you want, well, so be it.  I don't, and don't want my local politicians supporting him in our out of "the office".
