More information does not necessarily lead to a better vote (where "better" is defined as the vote that the voter would pick were they in possession of all relevant information).

To illustrate, imagine two candidates: candidate A, who looks like a regular politician, and candidate B, who looks like a serial killer. In the absence of any further information, you vote for candidate A.

Now imagine you read an entirely truthful pamphlet detailing guy A's trust fund excesses and other misdemeanors, while helpfully mentioning that guy B volunteers in a homeless shelter in his spare time. You switch your vote to guy B.

But it transpires that guy B occasionally abducts and murders the odd homeless person. He really is a serial killer! So your initial, "uninformed" vote was correct, and moreover correct for the right reasons, despite being strictly better informed after reading the pamphlet.

Trump will certainly have skeletons in his closet too.
