I think Landrieu may be lying, but we'll see. It seems likely that Obama will veto it anyway, but not necessarily on the grounds of how it affects climate change. There's a strong argument to be made that this vote violates the separation of powers, and that Congress shouldn't be able to override the decisions of an executive agency. Via CNN:
Washington (CNN) -- Louisiana Democratic Sen. Mary Landrieu says she has the 60 votes she needs for the Senate to advance a measure Tuesday that would authorize construction of the Keystone XL pipeline.
Landrieu has been scrambling to attract at least 15 Democrats to join 45 Republicans to reach the critical 60-vote procedural threshold. She told reporters at the Capitol on Monday night that she'd reached that mark.
"I feel very comfortable," Landrieu said.
At least 14 Democrats have said they will support the measure. But it's not clear who has agreed to provide the final vote or whether Landrieu's comments simply reflect optimism.
One of Landrieu's top targets, West Virginia Sen. Jay Rockefeller, said it won't be him. Another target, Maine Sen. Angus King, an independent who caucuses with the Democrats, said he is leaning against supporting the bill.
If she can shepherd the legislation through the Senate, it would allow Landrieu to demonstrate her influence one last time ahead of a Dec. 6 run-off election in Louisiana, where she faces Republican Rep. Bill Cassidy, who sponsored the bill authorizing the pipeline when the House approved it on Friday.
