Dave, you need to take this advice. Seriously. When it comes to politics just keep your mouth closed. You come off as a complete neophyte dolt. When you had the candidates on during the election you came across as a biased hack.
When you had Obama on what occurred should have been done in private. It was a torrid love affair of epic proportions. The MPAA would have rated it R for sexual content. Seriously, Michelle should have been jealous. I could hear her in the green room going "oh no he didn't! Not with my man he didn't!" I thought you two were going to start making out.
Then with John McCain you came across as a crass, uninformed, brain-washed, biased hack. You were rude, sarcastic, abrasive, and a complete curmudgeon.
I understand that you are a liberal. I understand that you are a Democrat. But you have to realize that half of your audience is neither of those things. Why alienate and turn off 50% of your possible viewers?
And then your attacks on Sarah Palin are beyond the pale. Especially the latest attack regarding "Alex Rodriguez knocking up her (Palin's) daughter". Dave, you may not be aware that the election is over, Obama won, and Governor Palin went back to Alaska. You don't have to continue to try to tear her vice-president candidacy down. Move on.
And then your phony "apology", followed by your phony "invitation" to cover your tracks made you look even worse. You are an irrelevant little twit of a man. You are insignificant to 99.99999% of the general population. Heck, your show isn't even funny any more.
Have you considered retirement? You had a near miss once with a persistent stalker. Remember that? She broke into your house she was so obsessed with you. It could have easily turned into a scene out of Stephen King's Misery. Retirement might be the safest solution at this point.
So Dave, fade away into the sunset. Try to have as much class as Jay Leno had and quit while you are ahead. As slim (or nonexistent) as your lead might be.
