Sen. John Thune, R-S.D., announced today that he will vote against Sonia Sotomayor's confirmation to the Supreme Court, becoming the seventh senator to do so.

"Her statements during the confirmation hearing before the Judiciary Committee do not always match the philosophies she has expressed prior to this hearing, such as her application of foreign law," Thune said in a statement released this evening.

Thune has been one of the more outspoken GOP senators throughout the nomination process, even going so far to launch a Web site tracking Sotomayor's confirmation. After meeting with her in late June, Thune said he had his concerns but was reserving judgment until after the hearings. In his statement today, he criticized her "narrow view" on the Second Amendment and what he sees as her tendency to inject personal feelings into judicial decision-making.

Thune is the ninth senator since the hearings ended Thursday to officially announce how he will vote. He joins Minority Leader Mitch McConnell, R-Ky., and Sen. Robert Bennett, R-Utah, who also announced their opposition. Other senators to officially say "no" so far are Jim Bunning of Kentucky, James Inhofe of Oklahoma, and Sam Brownback and Pat Roberts of Kansas.

Assuming that all Democrats line up to vote yes (none have said they will vote no), the three Republicans who announced Friday their intent to vote yes -- Mel Martinez of Florida, Olympia Snowe of Maine and Richard Lugar of Indiana -- have guaranteed at least 61 votes for Sotomayor (assuming that ailing Democratic Sens. Edward Kennedy of Massachusetts and Robert Byrd of West Virginia miss the vote). Two Judiciary Committee Democrats, Arlen Specter of Pennsylvania and Ben Cardin of Maryland, also released statements on Friday expressing their intent to vote yes.

Moderate Republican Sen. Susan Collins of Maine told reporters today that she will announce her vote tomorrow morning. She is expected to support Sotomayor, despite raising some concerns about the nominee's "wise Latina woman" remark after their meeting in early June.

Judiciary Chairman Patrick Leahy, D-Vt., has scheduled a committee vote for Tuesday morning, but ranking member Jeff Sessions, R-Ala., appearing on CNN Sunday, sounded confident that the GOP members would seek to delay it a week, which they are allowed to do under committee rules. "I think the July 28 date will be the day that we'll look to have that vote," Sessions told CNN's John King.
