Teamsters President Jimmy Hoffa Predicts 'Civil War

First there was a Democratic representative saying "there will be blood." And now Teamsters union president Jim Hoffa is predicting a "civil war":

“This is just the first round of a battle that’s going to divide this state,” Hoffa told CNN on Tuesday morning. “We’re going to have a civil war in this state.”

They will both argue that they're speaking figuratively. But considering the violence the union supporters have already displayed, is that a valid argument?
