Final answer:
The Panic of 1857 and its impact on the American economy distracted the minds of northern politicians.
Step-by-step explanation:
The economic problems that distracted the minds of northern politicians during this time period were mainly related to the Panic of 1857. This financial crisis resulted in a decline in grain exports, selling off of American stocks and bonds by European investors, and the failure of American banks. As a result, hundreds of thousands of northern workers lost their jobs and the economy suffered.
The northern politicians were concerned about preventing future economic problems, so they pushed for an increase in tariffs and land grant measures for farmers, railroads, and colleges. However, their efforts were obstructed by the South, leading to increased sectional tensions.
In summary, the economic problems that distracted the minds of northern politicians during this time were linked to the Panic of 1857 and its negative impact on the American economy.
