[JURIST] Democrats in the US Senate spent Monday morning lobbying against US Supreme Court [official website] nominee Judge Samuel Alito [official profile; JURIST news archive] in their last efforts to block his confirmation [JURIST report] to the high court. The Senate will hold a cloture vote [Senate backgrounder] Monday afternoon and if Alito wins at least 60 votes, the final confirmation vote will be held Tuesday morning. Those opposing Alito's spot on the Supreme Court say he will endanger individual rights and liberties if appointed. US Sen. Edward Kennedy (D-MA) [official website] said Alito would not be part of the "continued march towards progress," and the Senate's only independent member, Sen. Jim Jeffords (VT) [official website], said Alito's confirmation would "unacceptably shift the balance of the court." Despite last minute attempts to block his confirmation, Alito's supporters claim he has more than enough votes [JURIST report] to secure his place on the Supreme Court. AP has more.
