(CNN) - Democratic National Committee member John Patrick, a 31-year member of the United Steelworkers union and vice president of the Texas AFL-CIO, officially announced his support for Barack Obama Thursday. The nod is Obama’s second superdelegate endorsement of the day.
Earlier Thursday, former DNC Chairman Joe Andrew switched his vote from Clinton to Obama. The superdelegate gap between Clinton and Obama stands at 18 in CNN’s latest count.
"Senator Barack Obama has spent a lifetime standing up for American workers, and he will be a crucial voice for us in the White House,” Patrick said in a statement released by the Obama campaign. “He has consistently opposed unfair trade deals that fail to offer protection to American workers - like NAFTA. Senator Obama has a real plan to put money back in the pockets of working families by restoring the manufacturing base in America."
Patrick had been a supporter of former Senator John Edwards’ presidential bid.
