Andrew Jackson was the seventh President of the United States from 1829 to 1837, seeking to act as the direct representative of the common man.
More nearly than any of his predecessors, Andrew Jackson was elected by popular vote; as President he sought to act as the direct representative of the common man. Decrying officeholders who seemed to enjoy life tenure, he believed Government duties could be “so plain and simple” that offices should rotate among deserving applicants. //

While "populism" means different things to different people — much like the left's definition of "inclusion" doesn't mean to the rest of us what it means to Democrats — here's how Merriam-Webster defines the term:

... a political philosophy or movement that represents or is claimed to represent the interests of ordinary people especially against the Establishment.

Populism usually arises from a general discontent. … People feel that things are out of control, socially and economically. … The idea that this is the fault of the meritocratic elite. //

As big as Donald Trump’s victory was, his conservative populism’s political potential is bigger still.

While the primary post-election focus has been on where Trump over-performed, there are significant areas where he underperformed too.

And if Republicans could capture some of the votes Trump left on the table, they could significantly exceed Trump’s impressive 2024 victory margin in the future.

There is no reason conservative populism should not have at least an equal appeal to moderates. After all, Trump was able to tie Harris among voters who said abortion should be legal in most cases.
