After he had lost a lot of momentum after the conventions by taking on the Khans and other errors, Trump got things back together. He did very well most of August and into September, gaining momentum back and even edging past Hillary Clinton in a number of the polls.
The came the debate. It was watched by around 90 million Americans. It was Trump's opportunity to really put Hillary away.
Of course, everyone knew the debate was going to be set up for Hillary, and Trump should have known it as well, and prepared for it. Instead, he was an amateur and did not do the hours of preparation necessary.
The moderator, of course, did not ask Trump important questions. Instead Trump was asked about completely inconsequential things like birtherism and tax returns. Trumps answers were off the cuff and unprepared....just as one might expect from an amateur. There was no effort to turn the questions back on the moderator as he probably should have done.
On the other side, Hillary was asked softball questions that allowed her to give canned responses consisting of the age old Democratic gobbledygook that they have been saying for decades without there ever having been any positive change. Trump was unable to really inject himself into that side of the debate.
This gave the advantage to Hillary, and she ran with it. She clearly was the "winner" of the debate.
The most important part of the debate from her standpoint was that she was able to lay a trap for Trump by asking him about "Miss Piggy." Trump fell for it. This move got Hillary inside Trump's OODA Loop just like he got inside the loops of so many of his Republican opponents in the primaries
Not only did he fall into the trap, like with the Khans, he kept doubling down on the issue instead of moving on. It became the "news" on the mainstream media for a week or more.
Trump lost all of the momentum and gains he had made. He is now back to the post convention situation with a lost lead and lost momentum......and just a bit over a month to go.
There are two more debates. Trump has to take them seriously and prepare while still getting out and campaigning. He also needs to get off Twitter. It only makes him appear to be not serious.
Can he do it? Maybe. There will be a lot more attacks on him from all directions. Will his ego and nature allow him to respond properly, or will he over do the response?
He is doing a lot of advertising into the election as he should. Most of the ads seem effective, but will be only if they are well placed and reach enough undecided voters.
This is an election between two very flawed candidates, one a rank amateur in politics and the other an experienced, hardened politician with a very shady, perhaps even criminal, background.
Who will win?
It is pretty easy to see who will lose.
