Looks like a bunch of subjective crap put together in order to sell a book.
How many elections have been that hard to predict since the 1980's? 1 Maybe?
You could have 10 people answer those same questions and get 10 different answers. So are the 13 Keys the important part, or are the subjective answers he gives to those keys the important part?
Picking Reagan twice, Bush I once, Clinton twice, Bush II twice, and Obama once wasn't exactly rocket science. Hell, the only incumbent that didn't win in that time frame was Bush I. And Key #4 looks like it was developed specifically with Bush 1 in mind, making me wonder how he had these keys put together and used since the 80's.
This is a thread based on a stupid gimmick to make money, and you shouldn't be surprised by the stupidity it's generated.
