Undaunted by this lack of confidence from his peers, Johnson continued to campaign to retain his office. Although his campaign was more vigorous than that of Van Buren, his behavior on the campaign trail raised concern among voters. He made rambling, incoherent speeches.

Charges he leveled against Harrison in Cleveland were so poorly received that they touched off a riot in the city.
