I'm not saying she isn;t popular, because she obviously is. I have no doubt that here support is deep among conservatives...but I suspect her support as a candidate isn't wide outside of that group.
Alaska electoral politics isn;t evidence that she is electable on a national level. 2006 was a good year no doubt for Palin even as a Republican, just as it was generally a bad year for incumbents. Susan Collins won reelection to a third term in 2008 by over 10%, defeating a dem congressman in a state that went for Obama by a wide margin. Despite all that, I wouldn't use Collins victory in Maine as an indication of anything just as I wouldn't use Palin’s victory in Alaska as anything.
Would I love it if Palin was to prove me wrong...absolutely. Am I ready to say that she is our only or best hope of actually winning...absolutely not.
