"Let’s be clear: Trump is no fluke. Nor is he hijacking the Republican Party or the conservative movement, if there is such a thing. He is, rather, the party’s creation, its Frankenstein monster, brought to life by the party, fed by the party and now made strong enough to destroy its maker. Was it not the party’s wild obstructionism — the repeated threats to shut down the government over policy and legislative disagreements; the persistent call for nullification of Supreme Court decisions; the insistence that compromise was betrayal; the internal coups against party leaders who refused to join the general demolition — that taught Republican voters that government, institutions, political traditions, party leadership and even parties themselves were things to be overthrown, evaded, ignored, insulted, laughed at? Was it not Sen. Ted Cruz (R-Tex.), among many others, who set this tone and thereby cleared the way for someone even more irreverent, so that now, in a most unenjoyable irony, Cruz, along with the rest of the party, must fall to the purer version of himself, a less ideologically encumbered anarcho-revolutionary? This would not be the first revolution that devoured itself......
We are supposed to believe that Trump’s legion of “angry” people are angry about wage stagnation. No, they are angry about all the things Republicans have told them to be angry about these past 7½ years, and it has been Trump’s good fortune to be the guy to sweep them up and become their standard-bearer. He is the Napoleon who has harvested the fruit of the Revolution.
There has been much second-guessing lately. Why didn’t party leaders stand up and try to stop Trump earlier, while there was still time? But how could they have? Trump was feeding off forces in the party they had helped nurture and that they hoped to ride into power."

Article is well worth the read. The problem didn't begin with Obama 7 1/2 years ago. But he added a hate figure to the mix.
