The correct answer is C) some voters do not understand the candidates’ views.
Using election results to measure public opinion is a challenge because some voters do not understand the candidates’ views.
The results of an election do not always confirm the public opinion in that specific moment because people have different motives to cast their votes on election day. Some people vote for the same party, not taking into consideration the candidate. Others vote because they like the candidate, not paying attention to the platform. Some others vote impulsively at the moment, not being so convinced.
