During Donald Trump’s four-year term, many new Republican candidates have been elected to Congress. Often backed by the former president from the GOP’s primaries, they were chosen for their devotion towards him and their support for his policies : moral conservatism and laissez-faire attitudes towards fiscal and environmental issues are old Republican tenets taken over by Trump, while nativist and economic nationalism (based on anti-immigration and protectionist policies respectively), as well as the portrayal of White people without college degree as an oppressed minority are fresh precepts brought forward by the former populist President.

From the 1920s to the 1980s, the American press followed strict discursive practices based on objectivity and fairness. Starting in the 1930s, the country's political center of gravity was on the liberal side and there were few overtly conservative media.

Donald Trump won the 2016 Republican primaries thanks to the mobilization of a specific part of the electorate: the white, non-college-educated, lower middle-class.

Three Republican presidential candidates have proposed a foreign policy agenda worthy of examination. Marco Rubio (who withdrew from the race on 15 March 2016) and Ted Cruz present well-defined political projects pertaining to different traditions of American foreign policy theory. Donald Trump’s approach is less clear-cut but also less traditional, between isolationism and profitability.
