From a column in the Washington Times by Mark Mix, President of National Right to Work:
In his book “The Audacity of Hope,” then-candidate Barack Obama, when talking about his relationship with Big Labor union officials, wrote: “I owe those unions. When their leaders call, I do my best to call them back right away. I don’t consider this corrupting in any way.”
He goes on to recount the many big wet kisses that Obama has given to the unions. For a handy list, check out this list from the Daily Caller.
