John Bolton Nomination: help from a RINO?

CNSNews reports that Lincoln Chafee, a moderate liberal Republican Senator from Rhode Island, is inclined to support the nomination of John Bolton to the post of US ambassador to the UN. That support would effectively sew up the nomination and Chafee would be well-advised to vote for Bolton. The groups currently running ads against Bolton in Rhode Island in an effort to sway Chafee are led by some activist coordinators that make MoveOn.org look nearly moderate.
