Help!! And a question...

First the help portion-
I would like to insert .mpeg and mp3 files into my blog but don't know how or if it's even possible. Suggestions anyone???

Now the question-
First let me qualify this by saying that I am not the most politically active person around. However, I do vote both locally and nationally, not generally along party lines. So I'm not completely ignorant in a political arena.
Having read quite a few blogs in the "BEF", I know someone out there will be able to help me out.
Is Democractic Party Chairman Howard Dean a complete kook like he seems? Or is he a victim of foot in mouth disease?
