Last Summer, after the Florida legislature, shot down a proposed constitutional amendment that would have banned oil drilling in state waters, then-Gov. Charlie Crist pledged to “give ‘em hell for it.”

Crist was back in Tallahassee today to fulfill that promise, though he said he was more concerned with giving the people a chance to vote on the measure. He joined former Chief Finacial Officer Alex Sink to rally support for a constitutional amendment that would ban oil drilling in state waters.

Drilling close to Florida’s shore would create “a risk we cannot afford,” Sink said, a point driven home for her by conversations with people who were forced to close businesses after the spill.

Supporters of the amendment are pursuing two tracks: State Rep. Rick Kriseman, D-St. Petersburg has introduced legislation proposing the amendment, and Crist, Sink, Democratic lawmakers, and former Republican Sen. Durrell Peaden are backing a petition drive to get it on the ballot.

I asked Crist whether he, as a one-time supporter of offshore drilling, could explain why state politicians would oppose a ban, considering that there simply isn’t enough oil in state waters to have a meaningful impact on energy supplies.

His answer was terse: ”I guess they didn’t see the oil spill,” he said.
