Sen. Benjamin Cardin (D-Md.) says he can support the bill if it provides more funds for public transportation, including at the state level.

He said this in the context of a response to Sen. Lamar Alexander (R-Tenn.), who wants the bill changed to a sector-by-sector (as opposed to economy-wide) cap-and-trade system. Cardin suggested that Senators shouldn’t be demanding extraordinary changes to the legislation and threatening to withhold support unless their demands are met.

My guess? Cardin’s suggestion is futile.
