Simon is absolutely right. This is BS from the get-go. The JW's do much the same thing when they try to explain away yet another prediction that proves false. I've actually heard from the platform, "Sometimes you can't understand a Bible prophecy until it is fulfilled." Well, duh! Anybody can point to some vague statement in the past than can be interpreted to fit the circumstances and say, "See! I told you so!" That approach defeats the whole purpose of "prophecy."
Trump didn't win in any landslide anyway. He did get the required number of electoral votes to win, but not by a huge margin. And it appears that Hillary actually got more popular votes that he did. Either way, it's much more of a razor thin victory than a landslide.
That said, he is in fact the President-elect. So we all have to just deal with it and do the best with whatever comes our way. He may surprise us. Reagan wasn't the greatest genius of all time, but (with Nancy's help) he surrounded himself with competent people and actually listened to them. I think Reagan's greatest strength (other than looking Presidential and being a gifted orator) was that he could give people an assignment and then get out of their way and let them do their jobs. I don't know if Trump can do that. We'll see...
By the way, this is not an endorsement of Trump, Reagan, or anyone else. All Presidents have their pluses and minuses, their devoted supporters and vehement opposers. This is just what I hope is an objective observer's viewpoint. I try to be pragmatic and just deal with the facts as they are. There are times when you can't change your circumstances, so you just adapt the best you can and move on. The main thing is to never give up.
