Pundit: Grenier will almost certainly not be elected as mayor. Although she says she believes in raising city employees' wages, it was only a few years ago that she was arguing that their wages should not be increased. Her claim that she has learned more about the issue since then -- though sincere -- will not matter to most voters, who will see her as insincere. Which one of the following principles, if valid, most helps to justify the pundit's reasoning?
A: Voters are unlikely to be influenced by what a politician's views were in the past if the voters agree with the politician's current positions.
B: Voters are likely to elect a politician who they believe understands their financial concerns.
C: Voters are likely to question the sincerity of a politician who does not hold the same beliefs they do.
D: Voters are unlikely to vote for a politician whom they perceive to be insincere.
