Thomas Friedman writes in The New York Times:

So Graham’s approach to bringing around his conservative state has been simple: avoid talking about “climate change,” which many on the right don’t believe. Instead, frame our energy challenge as a need to “clean up carbon pollution,” to “become energy independent” and to “create more good jobs and new industries for South Carolinians.”

I've always respected Lindsey Graham's willingness to depart from party lines to do what he believes is right.
