Once upon a time, there were green Republicans.
Like John McCain, who sponsored the first climate cap-and-trade bill in the Senate — before getting all bitter about that whole being-crushed-by-Obama thing.
Like former Florida Gov. Charlie Crist, who set bold targets for cutting his state’s greenhouse gas emissions — before getting walloped in a Senate race by Tea Party darling Marco Rubio.
Like Maine Sen. Olympia Snowe, who championed cap-and-trade and got high marks from the League of Conservation Voters — before getting fed up with Senate dysfunction and polarization and GOP anti-contraception lunacy.
