It looks like there's finally an answer to the Secret Holder mystery. TPMmuckraker is reporting that Ted Stevens is the man. This isn't really a surprise, what with Stevens being a petty curmudgeon, legendary pork-loving politician, and generally the worst senator in the country. It is odd that this article has gone unnoticed for the past couple of weeks while bloggers tried to eliminate senators one by one by calling their offices.
The entire secret holds thing seems very odd and mysterious to me. I have to admit, I didn't realize that legislation could be stopped in such an opaque way. And it's pretty funny that a piece of legislation encouraging transparency in government is being blocked by a "secret hold."
