Gerson, whom I've always held in high esteem despite his conservative stances, seems to have regained his senses:
Make no mistake. Those who support Trump, no matter how reluctantly, have crossed a moral boundary. They are standing with a leader who encourages prejudice and despises the weak. They are aiding the transformation of a party formed by Lincoln’s blazing vision of equality into a party of white resentment. Those who find this one of the normal, everyday compromises of politics have truly lost their way.
This is not even to mention Trump’s pledge to limit press freedom, or his malicious birtherism, or his dangerous vaccine skepticism, or his economic plans that would bring global recession, or his lack of relevant qualifications, or his temperament of brooding and bragging, egotism and self-pity, or his promise to emancipate the world from American leadership, or his accusation that Ted Cruz’s father was somehow involved with Lee Harvey Freaking Oswald.
Some are trying their best to act as though all this were normal. But we are seeing, in the words of G.K. Chesterton, “lunacy dancing in high places.” None of this requires a vote for Hillary Clinton. But it forbids a vote for Donald Trump.
