I posted the interview below, but then the illegal wiretaps story started to break so I knocked it down the list. In the meantime, I've been over at Al's WNJ blog commenting about how Castle is a fake moderate. I think he is a fraud based on his narrow margin votes. However, I believe that you can also make the case that he is a fake moderate based on one vote in particular. That was the vote to elect Tom Delay as the leader of the House majority.
This Jonathan Singer interview of former Rhode Island Attorney General Sheldon Whitehouse speaks to that issue.
Jonathan Singer: Many political pundits would say that Lincoln Chafee, just like his father, works with Democrats nearly as often as he does with his own party. Even in a state as blue as Rhode Island, how do you run against someone trying to position himself as an independent?
Sheldon Whitehouse: ...when all is said and done, once he has decided to organize the United States Senate under this right wing Republican leadership, all of his other votes - even if they appear defensible on the surface - are in fact window dressing because this leadership is what is setting the table in the Senate.
Just substitute the word "Congress" for the word "Senate" and this is 100% true for Michael Castle. In my opinion Castle's vote for Tom Delay is the most damming vote of his political career.
