The president of the American Federation of Teachers says that union members haven’t just cooled on Trump—they’ve turned on him. Union leaders and members now “know who the bad guys are,” says Weingarten, the longtime head of the American Federation of Teachers—President Donald Trump and the five justices who signed on to the court’s Janus decision in June. Early on, Trump’s support among organized labor was at astronomical levels for a modern-day Republican, with November 2016 exit polls showing him with the support of more than 40 percent of union households. A March 2017 Reuters-Ipsos poll gave him a 62 percent approval rating among union members, but by spring 2018, it had dropped to 47 percent. The union members who ruled out voting for Hillary Clinton don’t appear to be sticking around as the president actually moves forward on his trade war and economic agenda.  Weingarten says the combination of an antagonistic administration and hostile high court has driven union members to the barricades. And though she acknowledges that the AFT and its allies may now be in a fight for their existence, at least they’re in the fight.
