Bernie Sanders’ amendment would carve out a chunk of money from the subsidy package for low-and-zero-carbon technologies and earmark it specifically for wind, solar, and other renewable-energy companies. Lieberman opposes it on the grounds that (a) it’s too large a handout to wind and solar, and (b) he wants to wait to spell out the winners of the subsidies in order to keep a coalition of support (which includes an antinuclear faction) in the Senate together. That will pretty much kill the amendment.
Update: Yup, it’s dead.
