I think we are missing an opportunity here.
This is a wedge issue that conservatives can exploit against the democrats. The enviro-loons would like to kill all energy usage except windmills and solar. The labor unions know their miners need work in the coal fields.
We need to set them off against each other. The more effort they spend fighting with each other the less time they have to attack conservatives, and who knows maybe we will peel off a couple of conservative union members.
I dont know about peeling off conservative union members, but let them fight it out with the greenies and maybe some common sense will come to some rank and file union members. In the meantime, the left is confused and weakened.
