The @MachinistsUnion members have endorsed @JoeBiden. This is the only international union I know of that had rank-and-file members vote for who to endorse. Ballots were cast this week. (Most endorsements come from an executive board.) Union hasn’t yet released the full results.
I think it’s very cool that the Machinists did an endorsement by member vote. Not sure why more don’t do it: your members can’t complain about the endorsement being done in a smoky back room! Actually, I know exactly why more don’t do it.
Here are the full results. Biden beat Bernie 36-26. And Trump got 34. 
I should add here that voting was done after Super Tuesday, March 4-6, which would have impacted Warren’s share (she dropped out on the 5th)
Also, Trump getting 34% might sound like a lot, but I don’t think it is for a (mostly) industrial union. Frankly I would have guessed he’d get closer to 40%
