You have Trump because Obama wasnt able to appeal to middle america due to the blocking of the GOP House.
Obama wasnt able to appeal to middle america because globalization and technology are replacing jobs at an unprecedented rate.
Those people who refuse to move or get re-trained continue to blame Obama, when technology and society has made them unemployable.
And then you have the very successful campaigns of Trump and partisan political actions from the FBI.
I bet many of the people who didnt "trust" Hilary were also Sexist and didnt want to be lead by a woman.
Then you have the Christian ideologies who wont vote for the left based on single issues like abortion. When really like in Canada its to taboo of a topic to touch now anyways.
There are also many other reasons.
Best case. GOP has their way with America and then hopefully Americans will finally see the GOP for their true self.
Or worse case, the divisive politics continues and more home grown extremism grows rampant. Trump mis-places this fear on muslims "again" and convinces the America people to give up more of the "rights" for protection.
My 2 cents. Bridge the gap with your fellow cons. You need to be united as "divided people are easier to rule" - Trevor Noah
