Final answer:
The incorrect statement about the Whigs is that their strongest support came from the lower Northwest and the southern backcountry. The Whigs' base was mainly from regions like Northern Illinois and Ohio's Western Reserve, and they favored a strong federal government for promoting economy and morality.
Step-by-step explanation:
The statement that is NOT true about the Whigs is that 'The Whigs’ strongest support came from the lower Northwest and the southern backcountry.' The Whigs drew strength from various regions, especially areas like Ohio's Western Reserve and Northern Illinois, but their support base did not primarily originate from the lower Northwest and the southern backcountry. The Whigs were a party that argued for an active role of government in promoting economic growth through projects such as the American System. They also saw the government as a means to influence morality in society. About liberty, the Whigs saw a strong federal government as crucial to protect and promote economic and political interests.
During the Age of the Common Man and the presidency of Andrew Jackson, the Democrats, and the Whigs formed opposing views on the government's role, with the Democrats favoring a government reflective of the majority's will and supportive of common citizens, while the Whigs preferred a nationalist approach towards government intervention in promoting economic growth.
