It would imply no such thing. Voters do not have much incentive to make informed votes since the expected impact of their vote is very small. As a result, they tend to use their vote for signaling purposes, as a way to reflect the type of person they want to be, rather than based on what they anticipate the consequences of their vote will be. If voters are so astute and informed, how do you explain that they radically disagree on the consequence of various policies, and that their disagreement can be predicted based on their parent's politics? How do you explain that in polls, voters position align so well with the left-right axis? We aren't just talking about values here, but about a non subjective assessment of the consequences of policies. How odd that it would cluster in this way!
