Polk made his views known in his acceptance letter and through responses to questions sent by citizens that were printed in newspapers, often by arrangement.[97][98]
A potential pitfall for Polk's campaign was the issue of whether the tariff should be for revenue only, or with the intent to protect American industry. Polk finessed the tariff issue in a published letter. Recalling that he had long stated that tariffs should only be sufficient to finance government operations, he maintained that stance but wrote that within that limitation, government could and should offer "fair and just protection" to American interests, including manufacturers.[99] He refused to expand on this stance, acceptable to most Democrats, despite the Whigs pointing out that he had committed himself to nothing. In September, a delegation of Whigs from nearby Giles County came to Columbia, armed with specific questions on Polk's views regarding the current tariff, the Whig-passed Tariff of 1842, and with the stated intent of remaining in Columbia until they got answers. Polk took several days to respond and chose to stand by his earlier statement, provoking an outcry in the Whig papers.
