Brief Explanations:

Supporters of the spoils system, most notably Andrew Jackson, argued that it promoted democracy by opening up government positions to ordinary citizens rather than a permanent class of elite bureaucrats. This practice, known as rotation in office, was intended to make the government more responsive to the popular will expressed through elections. While it did reward party loyalty, the primary ideological justification used by its proponents was the expansion of democratic participation and the prevention of entrenched political aristocracies.
