When I try to vote for / against a candidate in the primary election phase, e.g. the election on Code Review and don't have the sufficient rep (which is 150 in case of Code Review), the popup misleadingly tells you that "Vote up / down requires 150 rep" and links to the /help/privileges/vote-up and /help/privileges/vote-down respectively.
Which is actually wrong and the linked pages obviously tell that voting up / down requires 15 / 125 rep accordingly.
The sidebar tells however, that to vote for a candidate, you need 150 rep:
Any community member with 150 reputation may vote in the primary.
Though, as the wording of the error popup is still misleading, I'd propose to change it to something like:
Voting for / against the candidates requires 150 reputation
(probably it can be shortened a bit, as looks quite long)
