After the United Auto Workers labor union announced its endorsement of Joe Biden’s reelection campaign this week, the head of the UAW admitted that most members won’t likely vote for the Democrat president.

On Wednesday, after months of delay, the UAW labor union leadership announced that it had formally endorsed President Biden’s re-election bid.

Biden was expected to receive the endorsement last year but was withheld over concerns about his electric vehicle policies.

However, as UAW President Shawn Fain acknowledged in an interview, just because the union leadership endorsed Biden doesn’t mean that union workers will automatically fall in line to vote for him, Newsweek reported.
