Step-by-step explanation:
Based on the fact that the song was sung by Jackson supporters, it can be inferred that their opinion of Adams's education was that they wanted a president who would fight for them. Jackson's supporters saw him as a champion of the common man and believed that Adams, with his elitist background, was not the right candidate to fight for their interests. This can be seen in the slogan of the campaign, 'Adams who can write/Jackson who can fight,' which emphasized the contrast between Adams the aristocrat and Jackson the frontiersman.
