An earlier post has a link to the LIddy letter - his web site. When I could still listen to his show, he would have a lot of good comments about Watergate and John Dean.
The wind has to be blowing in just the right direction for me to get his show. I tend to believe his accounting of the events, but the whole thing still seems pretty ridiculous, or maybe after 8 years of Clinton I have simply become immune to impropriety. I still don't see why Nixon was brought down by it! It simply does not make sense.
