Soon after Brexit, the second largest surge in lookups this year for the term xenophobia leads us to the 2016 US presidential race. On June 29, President Obama gave a speech in which he expressed concern over the use of the term populism to describe Donald Trump’s political rhetoric. Obama insisted that this was not an example of populism, but of “nativism or xenophobia.” The biggest spike in lookups for the term populism occurred on June 30 as a result of Obama’s speech.
The Dictionary.com selection is in contrast to Merriam-Webster, who has asked the internet to look up words other than "fascism" in order to "improve the outcome" for their word of the year.
