Yes, Journalists who exposed the industrialists, politicians, and wealthy who exploited the masses were indeed called mugwumps. The term "Mugwump" originated in the late 19th century in the United States. They were a group of independent-minded intellectuals and reformers who opposed the political machines and corruption that were prevalent in American politics at the time.

Mugwumps were typically well-educated and came from prominent families. They were often drawn to reform causes, such as civil service reform, tariff reduction, and the regulation of big businesses. They were also critical of the political patronage and spoils systems that rewarded party loyalty over competence.

The term "Mugwump" was initially used in a derogatory sense by political insiders, but it was later embraced by the reformers themselves as a badge of honor. Mugwumps were influential in pushing for political reforms and ethical standards in government and played an important role in shaping American political discourse during the late 19th century.
