[JURIST] In his weekly radio address [text] Saturday President Bush urged the US Senate to vote on his nomination of Judge Samuel Alito [official profile; JURIST news archive] to the US Supreme Court, insisting that senators had a "constitutional responsibility" to do so and implicitly warning against any Democratic Party filibuster. Democratic Massachusetts Senators John Kerry and Edward Kennedy have planned a last-ditch effort to talk out the nomination [JURIST report], a strategy that can only be defeated if 60 Senators vote against it. Eight Democrats have said they will vote in favor of Alito, virtually assuring Alito’s confirmation [JURIST report] in the Republican-controlled upper chamber on the basis of a up-or-down majority vote.
