Since MJ Ray seems to think that anyone who doesn't vote for him but doesn't tell him why is a coward, I'm going to be up-front about it so I can't be accused of cowardice.
Elections are all about everyone making their own decision, for their own reasons, in the hope that the aggregate of those decisions will produce a useful and workable result. (Whether that happens in reality is a whole other issue). The individual's decision is a statement of their opinion, nothing more. Adding confidentiality to the voting process is meant to remove any pressure from the voter to make a decision on any basis other than their own opinion. Complaints about it like this from a candidate is pretty weak:
There seem to be some 30 or 40 voters who really dislike me, but didn't tell me that straight, preferring to be silent then vote me down. Are you cowards, or what?
Given this outburst, I'm hardly surprised that people weren't keen on telling Mark upfront that they weren't going to vote for him.
(As a disclaimer, I didn't vote in the SPI election, because I don't have a specific opinion on any of the candidiates' suitability for office on the SPI board.)
