I get the feeling this won’t stop Reid’s hypocritical attacks on the Koch brothers for doing the same thing as Steyer.

Via NY Times:

Tom Steyer, the billionaire climate activist, recently contributed $5 million to a “super PAC” dedicated to keeping Democrats in control of the United States Senate, cementing his alliance with the party as the 2014 campaign swings into high gear.

Mr. Steyer, a retired hedge fund manager, has used some of his fortune in an effort to make climate change a more potent political issue in pivotal states like Florida, Iowa and Virginia. He is planning to raise $100 million to run campaigns on climate issues, including efforts to persuade lawmakers and the Obama administration to block the proposed Keystone XL pipeline. […]

Mr. Steyer’s own super PAC, NextGen Climate Action, has also begun running climate-themed ads. Chris Lehane, a spokesman for Mr. Steyer, said the contribution did not mean that Mr. Steyer would go easy on Democrats who disagreed with him, like Senator Mary L. Landrieu of Louisiana, who has supported the Keystone project.

“A contribution to Senate Majority PAC, the way they spend it and use it, will be consistent with the criteria that we use to choose our states,” Mr. Lehane said. “And we are going to be doing our own separate campaigns.”

But the timing of the donation may spur renewed attacks on Mr. Steyer from Republicans, who have sought to paint him as a one-man special interest group using his money to get Democrats to stop the Keystone project. On Monday, a bipartisan bill to encourage energy efficiency died after Senate Democrats blocked efforts by Republicans to add amendments that would require approval of the pipeline, which would carry carbon-heavy crude from Canada’s Alberta oil sands to Gulf Coast refineries.
