United Auto Workers President Shawn Fain has been in the news almost nonstop for successfully negotiating a new contract for union members and, most recently, endorsing President Joe Biden for re-election.

But that endorsement is at odds with many rank-and-file union members who support Donald Trump. And Fain's next industry battle could be much harder.

In setting his sights on electric vehicle makers like Tesla and rallying his union members (many in swing states) around Biden, Fain is trying to propel the UAW back to its former industry might and political sway.
