David Letterman is gone and will be forgotten in a year. His impact will be zero.
He's already been forgotten...at least by me. I can state that I have never watched any of the programs he's hosted. My sole knowledge of that leftist scum, Letterman, comes from what's posted here on Free Republic. My idea of worthwhile viewing is the Sarah Palin Channel.
Her programs on that channel are unfailingly pro-God, pro-life, pro-gun and anti-sodomy. And there are occasional moments of good, wholesome humor where Governor Palin displays her incisive wit. Commie Letterman, purported to be "funny", can learn a thing or two about jokes from Governor Palin.
