Obama legacy already crumbled a year ago. His chosen successor, already highly flawed, was destroyed. 

After 8 years of Obama, Americans discovered what was voiced quite loudly in Canada as I recall. Across the spectrum, Canadians called Obama just a big talker with nothing inside. Canadians never like or trust big talking politicians, and never elected one to high office. We want substance. But Americans are quite different. They love big talkers. They immerse themselves in a culture of big talk and recklessness. So they elected an Obama. Who produced nothing. 

But look what they did. They elected another big talker again! Keep doing the same thing but expect a different result. It's the culture.
