Which logical fallacy is at play when concluding that a dislike for the mayor's job is implied by voting against his amendment?

The logical fallacy present in this scenario is a non sequitur. This fallacy occurs when a conclusion does not logically follow from the preceding statements or arguments. In this case, the assumption that voting against the mayor's amendment implies a dislike for the mayor's job does not logically connect the two ideas. A voter might oppose the amendment for various reasons that have nothing to do with their feelings about the mayor's role. Thus, the conclusion drawn is unfounded and demonstrates a breakdown in logical reasoning, characteristic of non sequitur fallacies.
