Looking at this country now ,not all people want to move from the state we are to the next level
I expect that you mean your country is Nigeria, since it is the only country, as far as I know, in which presidential elections are held, which began yesterday, Saturday. Isn't it?
In the Nigerian example, the hypothesis of the candidates' offer to buy votes is very candidate, since there are 18 candidates competing for one seat (presidency). Of course, this falls within the list of political corruption, because a person who works to buy votes from voters to ensure victory means that he is not eligible for that position.
As for the voters, they are also involved in corruption if they accept to sell their votes at any cost.
One of the reasons why people sell their votes is that they assume that their votes wouldn't count. These corrupt politicians have devised means to manipulate electoral results to suit their preferred candidates. Some electoral officials collect bribes from politicians to influence the election results. And this is what is happening right now in Nigeria. Electoral officials have refused to submit the election result to the central server because they have been induced to claim that there is no network. This gives them the privilege of changing the results and sending the fake one to the server.
When people see all these electoral malpractices, they just decide to sell their vote because with or without their vote, the winner of the election has already been predetermined.
It would be disgusting for someone to eventually sell their votes for peanuts after 8 years of living in hell as a Nigerian citizen. Anyone proven to have sold their votes demonstrates that they don't care about the future of the nation but instead enjoy suffering.
vote buying is now a custom in Nigeria politics, voters do not wait to be Given bribe again, they now demand as if it's their right to be given money before casting their vote. I blame politicians less in this evil act. Citizens voters education should be taking serious. Because the citizens are worst than the politicians, they're ready to sell their vote with a little money and suffer in the hands of same politicians for fours years.
That was in the previous elections not in this election. People turned out in large numbers to cast their votes for the best candidate in the current election without accepting or soliciting bribes in exchange for their participation in the country's election.
Nigeria's sole current issue is that politicians use military personnel to oppress the public through INEC in order to skew the results in their favor.
