C-SPAN has confirmed that at least 61 Senators intend to vote for cloture, moving forward the nomination of Solicitor General Elena Kagan to be an Associate Justice of the United States Supreme Court. Of these, only Sen. Ben Nelson (D-NE) says he then intends to oppose Ms. Kagan in the final confirmation vote, which only requires 50 Senators to approve the nomination.
C-SPAN’s confirmed tally for the final confirmation vote commitments now stands at 60-33. See member-by-member commitments at http://c-span.org/kagan.
