Today, Senator Lamar Alexander (R-TN) announced that he is endorsing Sonia Sotomayor for the SCOTUS. This comes after TN Senator Bob Corker announced that he would not vote for Sotomayor on the Senate floor. Alexander is notably the leader of the Senate Republicans Committee and is considered a major force in the GOP. His endorsement may help tip the scales of some Senators that were still undecided.
Currently, Senator Alexander joins Republican Sens Collins (ME); Snowe (ME); Martinez (FL); Graham (SC); and Lugar (IN) in voting for Sotomayor.
Corker, Burr (NC), DeMint (SC) are all Republicans that have voiced publicly that they will not vote for her.
