The response that best explains how the election of 1796 increased political tensions is:
President John Adams and Vice President Thomas Jefferson belonged to different political parties and did not agree on government policy.
This election marked a significant moment in American political history as it was the first time the presidency and vice presidency were held by members of different political parties (Adams was a Federalist and Jefferson was a Democratic-Republican), leading to increased partisan conflict and tensions in the early years of the republic.
