The least relevant piece of evidence included in the second paragraph is:
"And finally, our neighboring town of Westmont also named its library by a vote."
This statement does not provide strong support for the speaker's argument about the fairness and effectiveness of a voting process. It merely cites an example of another town's action, without explaining how that action contributes to the overall validity of the proposal to hold a public vote in the current town. The other pieces of evidence focus more directly on the benefits and positive outcomes of the voting process itself.
