Palin's Lies, Ctd

Here she is last year:

"I'm not a doom and gloom environmentalist like Al Gore blaming the changes in our climate on human activity."

Here she is this morning:

"I believe that man's activities certainly can be contributing to the issue of global warming, climate change."

Was she lying then or lying now?

Or is she just desperately saying whatever gets her through the next news cycle and hoping we don't have Google? I mean: seriously. She is in meltdown.

And one more thing: do you think the McCain campagn, running on the surge and for urgent action on climate change ever knew that she was once against the surge and denied that humans had any impact on the climate? Did no one vet her at all?
