Karen Tumulty wasn’t buying Bernie’s “political revolution” answer on climate change.

When the Washington Post’s Tumulty posed a question to both candidates at the Democratic debate about how they would combat climate change without bipartisan consensus on the issue, Sanders gave a very Sandersian response.

“What they are really saying is we don’t have the guts to take on the fossil fuel industry,” he said. “You know what happens to that Republican who listens to the scientists? On that day, the Republican loses his campaign funding from the Koch brothers and the fossil fuel industry.”

In order to change that, “we need a political revolution,” he said.

In Florida, rising sea levels are an immediate concern, and a coalition of the state’s mayors fought hard to have climate change questions included in the debate. Sanders’s revolution answer was a bit of a cop-out, and Tumulty let him know.
