This JURIST post has links to the executive order from Tennessee's Governor Bredesen postponing any Tennessee executions at least until May while a study is made of how the death penalty is administered.
On Friday, the Washington Post had this article, with comments from Governor Kaine questioning the need for new Virginia laws expanding the crimes for which the penalty of death may be sought. The article by Michael Shear begins: "Virginia Gov. Timothy M. Kaine, who ran for office pledging to enforce the death penalty despite his personal opposition, said he has strong reservations about efforts by the General Assembly to expand the crimes that are eligible for capital punishment."
Professor Berman has this interesting post on "the federalization of the death penalty."
