Well, her adversaries were upset:-
Some American Jews, like Rabbi Jeffrey Falick of TheAtheistRabbi.com, feel that Palin is merely in Israel "for her own gain, unrelated to the best interests of Jews, Palestinians or anyone else in the region." Falick, for one, wishes that Palin would "take off" the star.
The Atlantic blogger Andrew Sullivan posted a response from a reader echoing Falick's sentiments: "I don't know if there [are] rules about this, but as a Jew, I find it offensive that Sarah Palin is out wearing a Star of David."
The Washington Post got up a slideshow of politicians at the Western Wall but Palin went to the tunnels, not the outside wall and she went to see the "cornerstone" element, not the regular "take-my-picture-at-the-wall" visit. Which is indicative of a depth of feeling and identification that is different.
