Roger Kimball has in mind, here, the attacks on Donald Trump:

The disappointing thing is how many Americans just don’t care, because the Democrats have whipped them into a frenzy of hatred.  We are fortunate, indeed, to have basic rights protected in our fundamental laws, but no piece of paper can withstand the desire of a mob when it takes power.  If too many people allow their principles to be corrupted, and if too few speak to uphold those principles that once were shared, the mob will have its way.
