I believe that showing the post score for nomination posts during primaries is a bad idea.
When I loaded the primaries page during the election, the first thing I saw was a post voted -1. This immediately colored my impression of the post. Reading his post didn't indeed make me wish he was a moderator, but at the same point I couldn't bring myself to click on the down arrow. He wasn't an awesome candidate, but he wasn't a -2 score candidate either. Actually, I kinda wanted to sympathy upvote instead.
I want to judge by myself whether a candidate is worth or not my +1. For some of those people I don't have an opinion already, and I want to form one on my own. I don't want game theory to kick in, I don't want to be tricked into sympathy upvotes.
Having those numbers in large print as the first thing I see about them honestly prevents me from doing so. I'd rather have their avatar there.
Some people on chat do not agree with me; others want those scores to be completely public. I imagine they'll post explaining why I want to be aware of their opinion while forming my own.
Regardless of the discussion here, if you do prefer to hide the scores as you vote, here's the jQuery oneliner that does just that:
