Based on the information provided, it seems like the answer would be the freedom of the press.
The freedom of the press is a 1st amendment right that allows investigative journalists to spread information to the public about candidates and their policies. The ability to share this information without the threat of persecution is a critical element of having a fair election. The citizens should have all the information about a candidates policies/programs in order to make an educated decision as to who would be the best person for the job.
The majority of Populist Party members were "farmers," since the Populist Party made an effort to defend the rights of the "common man", as opposed to the rich.
So here's one advantage for each:
The south had a large amount of slaves that they could have in their workforce.
The North had way more rails and were able to transport supplies easier.
Hope this helps!
