I've seen some rumors that Big Labor will cave on on their opposition to taxing "Cadillac plans" in exchange for a push by Lord Zero to get card check passed.
Believe it. Allowing the taxing of "Cadillac plans" also fits nicely with their ultimate "single payer" goal as well. by taxing them, they push up the costs, overload the system, and when they collapse the system, gub'mint run health care swoops in, goes , "tsk, tsk, tsk; we tried the market approach and the market failed", and imposes nationalized health care on the ruins. Gub'mint wins; the unions are relieved of the burden of health care for their proles. Everybody - that matters - is happy.
