Republicans are increasingly uneasy in a world of change. That uniquely American sense of optimism that was once claimed by both Democrats and Republicans has been replaced with a dark foreboding of what lies ahead for a threatened America. No longer is to be born in America to win life’s lottery and know you are among the luckiest on earth; in the Trump Republican view, Americans are suckers, victims, the mark for a hostile world. Everyone is out to get America, from the Canadians to the Chinese. Anger has replaced gratitude.
