Letterman's hardly the first late night comic to use Palin progeny as a punchline.

Last September, just days after Palin burst on to the national scene, then-"Tonight Show" host Jay Leno cracked a joke that implied Bristol Palin's baby daddy was actually a famous politician.

Sarah Palin purposely tries to turn different segments of American society against each other.

I'd also like to add a complaint against Todd Palin's decision to denounce Letterman publicly and to inject the word "rape" into the discussion.

Letterman's jokes never came close to implying any sort of rape, and for Todd Palin to introduce the idea of his 14-year-old being raped into the public debate is just plain wrong.

if Todd Palin really did think Letterman was joking about the rape of his 14-year-old, why didn't he pick up the phone and demand to speak to Letterman directly in order to defend his daughter's honor?

You don't score political points or rally the base if you keep truly private matters private.
