Final answer:
The incorrect characteristic regarding Henry Clay's 1832 campaign is that he had a substantial advantage in political support from the west and the south over President Andrew Jackson, who actually maintained robust popularity in these regions and won the election.
Step-by-step explanation:
The characteristic that was not true of Henry Clay's election campaign of 1832 is: c. a substantial advantage over president Andrew Jackson in political support from the west and the south.
Henry Clay ran against Andrew Jackson in the presidential election of 1832. Clay's campaign hoped to leverage the controversy over the Bank of the United States (BUS) to their advantage. However, Jackson, the incumbent president, remained exceedingly popular and held significant support in the West and the South. This popularity was demonstrated by his decisive victory in both the popular vote and the Electoral College.
Furthermore, the intense rivalry between Andrew Jackson and Henry Clay can be traced back to the so-called 'corrupt bargain' during the 1824 election, where Clay's support helped John Quincy Adams win the presidency over Jackson in a contingent election held by the House of Representatives.
