Answer: Populism from the Latin word "Populus," which in translation would mean the people.
Explanation:
Similar to the notion of democracy, populism implies a rule that is in the service of the people. It is the opposite of government, which includes in its interest group a small group of people whose interests are defended, which is the case with aristocracy and plutocracy. And if they are similar synonyms, democracy today implies positive connotations in public, while populism is taken in the context of the negative.
This is because the strategy of populism is based on using the sensibilities of society, their essential life issues for political purposes. For example, it is possible to take two groups, which are separated by different antagonisms. On the one hand, it is an ordinary people and on the other a corrupt elite who argue that politics should be an expression of the will of the people
The doctrine of popular sovereignty was used. That meant that people in those states could choose to vote to support slavery and since they were majority then slavery would be permitted. There were even states that were at first non-slave states but then things changed and they voted to introduce slavery into the state and people voted for this and supported this.
