The same delicate, precise formula that allowed the bill to succeed in that chamber won’t work in the Senate. For instance, more than a quarter of the bill’s House support came from the California and New York delegations whose members account for a fifth of the House. But those two states, notes Jay Cost of RealClearPolitics, make up just four percent of the Senate. A cap-and-trade bill that can’t pass the House by a big margin probably can’t pass the Senate by even a narrow one.
