From what I've been reading, all base LEC reps will be in their pilot lounges all month, to answer questions about the T/A. So when you go to work, find one and ask him why he voted the way he did.
They have each put out an explanation in writing, of how and why they voted. I think every single one, from every base, is already posted to the DALPA forum, so you can go there and read up on your rep's vote.
