As America woke to the news that Donald Trump had dispatched his eldest daughter, Ivanka, to fill in for him at a G20 meeting with world leaders, the response of people ran from outraged to stunned, and then back to outraged. Matthew Dowd, a political strategist who led George W Bush’s reelection campaign in 2004, said there would have been outcry among supporters of Mr Trump had Barack Obama or Hillary Clinton sent in their children. “Can you imagine what the GOP/Trump fans would be saying if this was Chelsea or Malia doing this? We are a Republic, not a monarchy,” he said.
