Final answer:
False. The Republicans did not oppose the 1776 constitution in Pennsylvania state politics.
Step-by-step explanation:
False. In Pennsylvania state politics, the Republicans did not oppose the 1776 constitution. Instead, it was the Conservative Whigs who opposed the constitution. They believed that it was too democratic and gave too much power to individuals who they believed were unfit to vote. The constitution eliminated the executive branch and the upper house, and had a unicameral legislature.
