Who was Andrew Jackson's second term vice president, often referred to as "The Little Dutchman"?

Andrew Jackson's second term vice president was indeed Martin van Buren, who is often referred to as "The Little Dutchman." This nickname comes from van Buren's Dutch heritage and his background as a native of Kinderhook, New York, an area with a significant Dutch influence. His political career was closely intertwined with Jackson's presidency, as he played a crucial role in many of Jackson's policies and was a staunch supporter of the Jacksonian Democratic Party.

Van Buren's experience in politics, having served as the Governor of New York and in various other positions, made him a suitable choice for vice president during Jackson's second term. After Jackson's presidency, Van Buren went on to become the eighth President of the United States himself.

The other options listed do not apply to the role of vice president during Jackson's second term. John C. Calhoun, for instance, served as Jackson's vice president during his first term but resigned before Jackson's second term began. Millard Fillmore and Franklin Pierce were not connected to Jackson's administration at all in the context of the vice presidency. Therefore, the reference to "The Little Dutchman" directly aligns with Martin van Buren, making him the correct answer.
