The exact terms of what makes up Trumpism are contentious and are sufficiently complex to overwhelm any single framework of analysis;[1] it has been called an American political variant of the far-right,[2][3] and the national-populist and neo-nationalist sentiment seen in multiple nations worldwide from the late 2010s[4] to the early 2020s. Though not strictly limited to any one party, Trump supporters became a significant faction of the Republican Party in the United States, with the remainder often characterized as "establishment" in contrast. Some Republicans became members of the Never Trump movement, with several leaving the party in protest.
Other terms used to describe the movement include: America First and MAGA.
