Those who supported the purchase argued that it was a good deal for the United States. They said that Alaska was a vast territory with a lot of natural resources, and that it would be beneficial to the country to own it. They also said that the purchase would help to secure the country's western frontier.
Those who opposed the purchase said that it was a waste of money. They argued that Alaska was too far away to be of any use to the United States, and that the country could not afford to buy it. They also said that the purchase would increase the country's debt.
In the end, the United States Senate approved the purchase of Alaska by a vote of 37 to 2. However, the purchase remained unpopular with many Americans for many years.
