While I'm not in the union, I would suspect that the million or so who didn't bother to vote are of the low information, don't know don't care crowd. My guess is a majority of those would have voted for Hoffa just on name recognition alone, and some others because they weren't pissed off enough to vote at all, let alone not vote for the status quo. The key isn't just getting all the members to vote, but getting them engaged enough to care and mad enough to do something about what has happened to y'all.
