Let's clarify something before we go any further.
The "selling" was done by Media. Be it Fox or CNN, they are the channel through which most people form their opinions. It seems stupid to me that it is so, but that is the way it is. So if you want to blame anyone other than yourself, it must be them, not the administration. As an adult, you are responsible for what you allow yourself to be fed.
With a minimum of effort, anyone can determine the real facts, without relying on the opinions of others. That is a personal choice, and if it is not done, then you have no one to blame but yourself.
Caveat Emptor applies to politics more-so than to consumerism.
