Final answer:
The 1968 DNC led to reforms in the Democratic Party, including the institution of new rules for selecting delegates based on primary performance.
Step-by-step explanation:
The 1968 Democratic National Convention led to important reforms within the Democratic Party. Following the chaotic Chicago convention, new rules were instituted for selecting delegates for future conventions. These rules awarded delegates based on candidates' performance in state primaries, which gave a greater voice to primary voters and reduced the influence of party leaders. This reform aimed to broaden participation and appeal of the party.
