One of the culture that is common with the yorubas, hausa and Fulani is that they will welcome and show respect for a presidential candidate of a party. Sometimes they may choose not to do that, because of one reason or the other, for example in the 2003 presidential election, massive crowd did rally walk for buhari in the north, but in the day of election, majority of the people in the north decided to vote for OBJ. Another example is in the 2019 election, where massive crowd came for the campaign of Atiku in the SW, NC, NE, and NW, but at the end of the day, majority of the same people decided to vote for buhari. Another example is the governorship election in Osun state, where many people from most of the local government area came out to show their support for the APC governor, but in the end of the day, majority of the people in Osun state decided to vote for the candidate of PDP, which looks like a vote against BAT APC, because the governor of osun state did perform well in his first term in office.
The money factor in campaign rally and city walk
Campaign rally and city walk also apply to the yorubas hausa and Fulani culture of showing respect for a candidate. Money factor is also something that makes people come out for campaign rally and city walk. A candidate with #50M for example can pay 10000 people with N5000 just for them to come out to support him with a city walk, that is why the best way to know if a candidate of a party has many supporters, is to check in their social media pages, to see how people from different part of the country are commenting there
