Glad to see Letterman retiring. There are lots of reasons why David Letterman should have been fired long ago: Be>1. Above all, he is NOT funny. He is a bitter, grumpy man.
2. His sexual harassment scandal. This went way, way anything Imus every said. Not no hysteria in MSM.
3. He has lied about various politicians running for office (all of the GOP), and he knew he told lies about them.
4. His long-lasting obsession with Christie, Palin and others that have crossed over to vindictive personal attacks.
