What's Going On, Lamar?

Lamar Alexander, my favorite U.S. senator (this is no big task considering the issues I have with my other U.S. senator, Dr. Frist), is one of 16 members of the Senate not to co-sponsor a resolution condemning the legislative body's inability or refusal to pass anti-lynching legislation during the 80 years-or-so that lynching (especially the lynching of African Americans) was a major problem in the U.S.

I'm planning to write Lamar a letter, but this info from AmericaBlog is not encouraging.
