(CNN) - One of the country’s biggest unions - the United Food and Commercial Workers Union - voted Thursday to endorse Barack Obama.
Obama’s Democratic opponent, Hillary Clinton, had also hoped for the union’s nod.
The union, which has more than a million members, is very active in Ohio and Texas - both contests the Clinton campaign is counting on to help her regain momentum in the Democratic presidential race.
It is also very strong in Pennsylvania, another major contest looming on the horizon, and is a major force in voter turnout in all three states.
The union represents workers in the meatpacking industry, in supermarkets and food processing.
