- Britannica:
. . . political program or movement that champions, or claims to champion, the common person, usually by favorable contrast with a real or perceived elite or establishment. Populism usually combines elements of the left and the right, opposing large business and financial interests but also frequently being hostile to established liberal, socialist, and labor parties.
- ECPS: Populism.
. . . refers to a range of political stances that emphasize the idea of “the people” and often juxtapose this group against “the elite”. The term developed in the 19th century and has been applied to various politicians, parties, and movements since that time, although has rarely been chosen as a self-description. Within political science and other social sciences, several different definitions of populism have been employed, with some scholars proposing that the term be rejected altogether.
A common framework for interpreting populism is known as the ideational approach: this defines populism as an ideology which presents “the people” as a morally good force and contrasts them against “the elite”, who are portrayed as corrupt and self-serving. Populists differ in how “the people” are defined, but it can be based along class, ethnic, or national lines. In other words, as Jan-Werner Müller stated in an article that the populist decides who the real people are; and whoever does not want to be unified on the populist’s terms is completely and utterly excluded — even if they happen to have a British or an American passport.

It is difficult to definitively characterize populism, but one helpful definition describes it as “reflecting a deep suspicion of the prevailing establishment, which is believed to conspire against the people instead of working in their interests.” Populists believe that the people, however defined, are the “true repositories of the soul of the nation.” Donald Trump’s frequent references to his supporters as “real” Americans are a classic populist rhetorical move.
The concept of populism has a distinctly pejorative connotation. It is a label that politicians apply to their opponents, but rarely claim for themselves (as Mudde and Kaltwasser aver). The fundamental claim of populism is that there is a singular “people” who are in opposition to “the elite.” The populist claims to be the representative of “the people.” In this way, a populist movement would describe itself as authentically democratic—in contrast with the “politics as usual” that only supports the interest of “the elite.”
Populists can be from the right or left of the political divide; left-wing populists (also known as social populists) combine left-wing politics with populist themes and rhetoric while right-wing populists (also known as national populists) do the same on the right side of the political spectrum.

. . . a range of political stances that emphasize the idea of "the people" and often juxtapose this group with "the elite". It is frequently associated with anti-establishment and anti-political sentiment. The term developed in the late 19th century and has been applied to various politicians, parties and movements since that time, often as a pejorative. Within political science and other social sciences, several different definitions of populism have been employed, with some scholars proposing that the term be rejected altogether.
A common framework for interpreting populism is known as the ideational approach: this defines populism as an ideology that presents "the people" as a morally good force and contrasts them against "the elite", who are portrayed as corrupt and self-serving. Populists differ in how "the people" are defined, but it can be based along class, ethnic, or national lines. Populists typically present "the elite" as comprising the political, economic, cultural, and media establishment, depicted as a homogeneous entity and accused of placing their own interests, and often the interests of other groups—such as large corporations, foreign countries, or immigrants—above the interests of "the people". Populist parties and social movements are often led by charismatic or dominant figures who present themselves as "the voice of the people". According to the ideational approach, populism is often combined with other ideologies, such as nationalism, liberalism, or socialism. Thus, populists can be found at different locations along the left–right political spectrum, and there exist both left-wing populism and right-wing populism.
