  David is Jewish name, by that you can see that he is a Jew.   David is a Christian name too. David Duke is a Jew?:eek: David Lane was a Jew??:rolleyes:     Also, to the OP, what makes you so certain that David Letterman is a Jew? I'm pretty darn sure he is German and British American from Indiana and a gentile who was raised in a Christian family. If he was a Jew I probably would've known by now because I have a mental list of practically every Jewish celebrity you could imagine and Letterman is not on my list. But his band leader Paul Shaffer is on my Jewish celebrity list.:D
