Who was milliard Fillmore running against in the compromise of 1850?

Millard Fillmore was not directly running against anyone in the Compromise of 1850, as it was a series of legislative measures rather than an election. However, he was President at the time and supported the compromise, which aimed to ease tensions between slave and free states. His predecessor, Zachary Taylor, had opposed the compromise, while Fillmore's support helped facilitate its passage through Congress. The key opposing factions included pro-slavery and anti-slavery legislators rather than specific individuals.
