To summarize the two campaign themes in McKinley's campaign:

1. "The Currency Question" focused on the debate between the gold standard and free silver. The gold standard supported using gold as the sole standard for currency, while free silver advocated for the unlimited coinage of silver alongside gold. This was a significant issue at the time as many farmers and laborers believed that introducing more silver into the monetary system would lead to inflation and help alleviate their debt.

2. "Protective Tariffs" referred to McKinley's support for high import tariffs to protect American industries and promote domestic manufacturing. The Republican Party, which McKinley represented, was known for its pro-tariff stance and believed that it would shield American businesses from foreign competition and maintain economic growth.

As for which theme was more significant, it is subjective and open to interpretation. The issue of currency had a broad impact on the entire economy, while protective tariffs primarily influenced international trade. It is important to consult multiple sources and do further research to determine the significance of each theme in McKinley's campaign.
