WASHINGTON (CNN) – Call it Kerry vs. Palin, Round 2.
Massachusetts Democrat Sen. John Kerry, a longtime Obama ally, and Alaska's Republican Gov. Sarah Palin are sparring again, this time over climate change and energy policy.
In her op-ed, Palin slams President Obama's cap-and-trade energy plan, saying she believes the plan is "an enormous threat to our economy."
In his response, Kerry takes a dig at Palin in an apparent reference to Tina Fey's "I can see Russia from my house" take-off on Palin.
"The global climate change crisis threatens our economy and our national security in profound ways," writes Kerry.
"Governor Palin need no look further than the view from her front porch in Alaska to see how destructive this crisis can be," says Kerry, pointing to a two-year-old New York Times report about a small Alaskan village facing destruction because of melting permafrost.
Kerry also takes issue with Palin's focus on the likely economic consequences of Obama's plan. "Reading Gov. Palin's op-ed too often it sounds like the only threats America faces are solely economic. But that's not what our intelligence experts and military leaders tell us," writes Kerry.
Kerry also says Palin is "wrong" about the job creation projected to occur under Obama's plan and about the fact that the plan will yield "new, clean energy sources."
The two pols sparred nearly three weeks ago when Kerry reportedly joked that it was Palin – rather than South Carolina's Republican Gov. Mark Sanford – who should have gone missing. In her counter-attack, Palin took a swing at the senator's face: "... [T]he way he said it, he looked quite frustrated, and he looked so sad, and I just wanted to reach out to the TV and say, 'John Kerry, why the long face?'" she joked.
