"The bill’s authors hope the concession to Florida will prevent a filibuster by Bill Nelson, D-Fla., another leading drilling opponent."
That's the same limit that President Barack Obama had proposed and that Nelson said he'd be okay with -- if the U.S. military, which conducts training sessions in the Gulf of Mexico, gave it the ok. The administration had pushed to drill at 45 miles off the coast, Nelson has said.
Nelson Tuesday tweeted his opposition to drilling: "Word is climate bill might let rigs in Florida’s no-drill zone. If Sens. Kerry, Lieberman are following me on Twitter: that’s a non starter."
