Summary:
1. Trump voters are not irrational, at least no more than Clinton voters.
2. The "what's the matter with Kansas" argument that poor conservatives aren't voting in their best interests is both wrong and insulting. Both sides often vote against their personal interests (poor pubs voting against handouts and rich coastal elites voting in favor of higher taxes) for the sake of what they view as more important things for society at large. Neither is more "rational."
3. The "Clinton had a better temperament" argument is likewise wrong. It all comes down to ideology. Thought experiment: if the election had been Cruz v. Sharpton, libs would still have voted Sharpton. Both sides vote on ideology, and equally rational.
4. Liberals are no smarter than conservatives, and certainly have no more right to consider themselves "the party of science" or masters of empirical, rational thought. A whole host of liberal positions defy well established research. Likewise, studies indicate that liberals are no more informed re current events.
