I seem to remember a big time House Speaker, Dan Rostenkowski who served time for corruption charges also writing ‘books’. They weren’t meant to be read so they had no reason to have any worthwhile content. They were meant to be bought by the labor unions, political favor-seekers and the like - by the truckloads.
Nice way to funnel clean cash to a politician, isn’t it?
That is what led to the downfall of ex-House Speaker Jim Wright.
