But they won't vote Republican

The Washington Examiner has a story about the Laborers International union, which naturally favors Keystone XL.  The Examiner cites union outrage over the Obama administrations latest stall on the pipeline.  But, despite outrage, the 557,000 member union never says to its membership "Vote a straight Republican ticket, that will get us Keystone XL and keep us off unemployment."   Here is a clear cut case where Republicans can help the union but the union people cannot drop their lifelong loyalty to the democrats.  These are clearly instinct voters, not thinking voters. 
  The Examiner goes on to explain the role of hedge fund billionaire Tom Steyer, who gave $50 million to Obama, and promised to raise another $50 million.  Obama clearly values the $100 million more than he values 557,000 live and voting union members.  I guess he figures they are all dumb enough to vote democratic no matter what.
