Trumka said he didn't know where Clinton now stood on the issue (Trade Deal).
"She's going to have to answer that," he said. "I think she won't be able to go through a campaign without answering that and people will take it seriously and it will affect whether they vote for her or don't vote for her."
If Clinton backs the trade pact and the fast-track authority, there will be costs, he cautioned. "It will be tougher to mobilize working people. It'll be tougher to get them to come out excited and work to do door-knocking and leafleting and phone-banking and all the things that are going to be necessary if she is the candidate and we endorse her to get elected. It will make it far more difficult."
It even is "conceivable" that the AFL-CIO wouldn't endorse a presidential candidate, he said, "if both candidates weren't interested in raising wages and creating jobs."
