Independent Senator Joe Lieberman of Connecticut on Sarah Palin, quoted in USA Today, April 13,"Lieberman: 'Everybody should listen' to Sarah Palin":

I think ... Sarah Palin for a lot of people has become a spokesperson. People worried that government has forgotten them, that it has grown too big, that the deficit is growing too large, and in some sense that we're not being as strong as we should be in the world — Governor Palin has spoken to those concerns as much as anyone.

I do disagree with her on some of the specifics that she has said, but I think anybody who underestimates Sarah Palin as a political force in America does so at some peril, because she is speaking for a lot of people out there.

Note - Palin has been a steadfast supporter of Israel. Late in the '08 campaign heavy internet rumors spread that she had a part Jewish ancestry on her mother's side. She never denied it. (Here's an article that delves into the question from Sarah Palin - 2008)
