Step-by-step explanation:
The county unit system favored the traditional branch of the Democratic Party by undermining Republican election efforts. The system was a method of voting used in some Southern states in the United States, which gave more power to rural areas, where traditional Democrats were more dominant, at the expense of urban areas, where Republicans and progressive Democrats were stronger. This allowed the traditional branch of the Democratic Party to maintain their hold on political power and win elections, despite challenges from other political groups.
