Big labor has been trying to push this through. If they couldnt get it done with a near super majority of democrats. I dont think it has a snowballs chance in hell with a republican house and potential republican in the WH. This is bad PR regardless of the democrats affiliation with big labor. Like the gun law debate. If they run on granting the ability of the union to browbeat you into voting for them. They will lose the next election.
