Final answer:
Progressives reduced political party control of municipal elections through nonpartisan elections and direct primaries.
Step-by-step explanation:
The progressives tried to reduce political party control of municipal elections through several reform measures. One of the ways they sought to accomplish this was by implementing nonpartisan elections, where candidates do not have party affiliations listed on the ballot. This aimed to prevent voters from simply voting along party lines without considering individual candidates. Additionally, progressives pushed for the introduction of direct primary elections, which allowed voters to directly choose their party's candidates rather than relying on party bosses and machines.
