Bolton nomination dead?

After Sen. Lincoln Chafee pulled his support for the nomination of John Bolton to continue to serve as US Ambassador to the UN, it appears there won't be a vote in the forseeable future, if ever. At the Washington Note, Steve Clemons posts that the nomination appears to be dead.

After the Senate didn't support Bolton's nomination in 2004, the president appointed Bolton as a recess appointment meaning his term expires at the end of this year unless the Senate supports him.

Chafee is in a tough primary battle to save his job in Rhode Island. If Republicans end up supporting Steve Laffey, it would almost certainly result in the Democrats picking up the seat in November.
