Sen. Claire McCaskill (D-Mo.) doesn’t think that the climate and energy bill that passed the House last month stands much of a chance in the Senate.
And if climate legislation is going to pass the Senate, it would have to have a “very gradual implementation,” McCaskill told conservative Missouri talk radio host Mike Ferguson on Tuesday. She also said she would not vote for the climate bill that the Senate rejected last year, nor would she vote for the House bill (Waxman-Markey) as it stands.
“If there is going to be enough support for the bill, it will be a very gradual implementation as we move toward changing to wind and solar and other kinds of energy,” said McCaskill. “I’m going to be one of those trying to craft it in a way that is very gradual, that is not going to hurt a state like Missouri that is so coal dependent.”
She said she will probably make those on the left and right angry in this debate, and will be “working with a group of moderates in the middle” to shape the Senate bill. She acknowledged that the science shows that action on climate change is urgent, and also that there is a need for the United States to be a leader in the world in crafting climate policy, but didn’t seem too interested in acting very quickly.

She voted against the stimulus. She tweets about earmarks. She goes against Obama on climate legislation. Ladies and gentlemen, we have the frontrunner for the Democratic nomination in 2016.
