The Democratic National Committee’s platform committee voted down the $15 minimum wage hike that Bernie Sanders has been fighting for throughout his left-wing populist campaign.

The platform’s inability to add the minimum wage hike could dampen Clinton’s chances to unify her party. Sanders is technically still running for president ahead of Philadelphia’s Democratic convention. Sanders has not endorsed Clinton, but said Friday that he will probably vote for Clinton. It is unclear whether Sanders still has a shot to win the Democratic nomination at a contested convention.
