Mine workers have yet to endorse Presidential Candidate

The United Mine Workers of America has not endorsed a presidential candidate, and it's not clear when the union will give either Mitt Romney or Barack Obama its backing. This is the first time in 40 years the miners' union has not endorsed a candidate. On Friday, the union announced it's backing Democrats in U.S. House and Senate races in 16 states. On its website, the union says neither Obama nor Romney "has yet demonstrated that he will be on the side of UMWA members and their families as president. The UMWA backed Obama in the 2008 election.
