I was going to wait until after the election to post this, but Mr. Taylor has stumbled upon the truth, so there isn't a lot of reason to hold it back: Much like the Bush family who have run a sleeper cell for the Democrats for decades, Mr. Trump is also a Democratic agent.
Watching the disastrous policies of the Republicans, he decided to try to pick up where the Bushes failed and totally destroy the GOP and, even more importantly, the tea party. So critical did he deem this that he decided to sacrifice his personal reputation for the good of the country. The road he took was not an easy one, and we must greatly admire his planning and dedication.
The first step was to obtain the GOP nomination. He astutely observed the political divides between primary voters and the general election. While the overall country wobbles from Center-Left to Center-Right, the primaries only attract the fringes. In retrospect, his plan should be obvious: Appeal to the worst fringe elements of the GOP thus preventing any viable candidates from winning the nomination.
In many respects this first step ought to have been the hardest. He had to present himself as insane enough to pick up the fringe, while not seeming so out of touch with reality as to lose the nomination. His fears were quickly dispelled however as it became clear that there was no such thing as too out of touch. If you go back and watch some of the earlier speeches you can see his growing panic and amazement that there was no actual bottom.
With the nomination in hand, things became much easier. He put his trust into the great American center to reject the caricature he had presented and to elect Hillary. To this end, he brought in a running mate with radical Anti-American views who was best known as the governor of a failed state.
Personally, I wouldn't have taken the risk. While most people take the VP as a joke position, he is the second in line, and there were good odds at that point that Donald might have actually won the election. With a more center running mate, he could have then simply dropped the persona he had displaying and go back to his Democratic origins. Still, he doesn't really want to be President, and is much more skilled at these kind of deals than I am, so I'm not a good person to second guess him.
It's also true that Mr. Trump knew he had several aces up his sleeve should it look like he might lose to Hillary. He has, in fact, been a Tony Stark-like playboy, and had a lot of bad history behind him. All he had to do was have old tapes released and it would totally torpedo any chance he might have had. As you can see, he ended up doing exactly that.
So here we are, on the cusp of electing our first female President and embarking on eight more years of peace and prosperity, and we owe it all to the sacrifice of Donald J. Trump.
