United Auto Workers members at Ford had enough votes to ratify their contract on Friday, the third and final automaker to join the fold — effectively ending a strike that drew wide political attention and solidified President Joe Biden’s alignment with organized labor.

Union members at General Motors and Stellantis hit the same milestones Thursday and earlier Friday, respectively, according to vote trackers from the UAW.

The votes mark the end of a tumultuous labor-management clash that drew in top lawmakers and Democrats including Biden, who made an unprecedented visit to the picket line and was deeply invested in the outcome. A prolonged strike threatened to further unsettle the economy and provide an opening for former President Donald Trump, who is courting the support of blue-collar workers in his bid to return to the White House.
