Important edit: As
Note that this is somewhat of an interesting election. Nominally, it's one of the "instant runoff" votes where voters rank the candidates, and the candidates who have fewest first-rank votes are eliminated and "their" voters have their second-rank votes taken as first-rank votes. If a voter has all three of their candidates eliminated, their ballot is discarded; when a candidate ends up with more than 50% of the top-rank votes on remaining ballots, they're declared the winner.
What's interesting is that it's not a closed-tally election. Anyone who has voted can (a) immediately see the current totals, and (b) change their vote. It's not currently possible to see exactly what will happen in the runoffs, but we can make some reasonable guesses on the bounds.
Meanwhile, regardless of how the runoff goes, it's currently a three-way race between

Thus, unless things change notably, the only votes that are likely to matter are votes for

However,
Old, erroneous analysis:
What's interesting is that it's not a closed-tally election. Anyone who has voted can (a) immediately see the current totals, and (b) change their vote. It's not currently possible to see exactly what will happen in the runoffs, but we can tell that it doesn't matter; there's nobody who is currently on the ballots of 50% of the voters (the leader's a bit over 40%), so the instant runoff can't pick a winner.
Thus, unless things change notably, the only vote that is likely to matter is your first-rank vote.
Meanwhile, looking at the first-rank votes, it's currently a three-way race betweenlegomymalfoy,
jameth, and
rm, in that order. Unless things swing dramatically, votes for anyone else are likely to only serve as endorsements of their position statements, which isn't likely to mean much.
Thus, unless things change notably, the only vote that is likely to matter is a vote forlegomymalfoy,
rm, or
jameth.
Personally, from a quick look through the position statements, I suspect that I would preferrm to
legomymalfoy, but I'm pretty sure either would do well, while it's clear that
jameth would not be an effective user representative, to say the least. Given the current totals, it seems pretty clear that
rm won't catch
legomymalfoy; their votes are running about 2.5:1 between them. There is some danger that
jameth will catch up, though; that ratio is about 1.5:1.
Also, I'll note thatrm is not that far behind
legomymalfoy in the runoff, since she's got quite a lot of second-rank votes; there's a very outside chance she could catch
legomymalfoy there and have more than 50% of the vote, if things do change a lot. This is not a likely scenario at all, but it's the most plausible way that a second-rank vote might matter at all.
Therefore, my practical endorsement is this: Votelegomymalfoy at first-rank,
rm at second-rank, and put your third-rank vote on someone you like.
Therefore, my practical endorsement is this: Vote
(See, this is much easier than trying to pick among the at-least-a-half-dozen really good candidates who are running!)
