Last week, the Republicans blocked the nomination of Patricia Millett to the U.S. Court of Appeals for the District of Columbia because Obama is trying to pack the court that has the most to say about his policies and the tactics used by his administration to do end runs around the law and the Constitution.
As a result, Harry Reid (who voted against Millett) is once again threatening the nuclear option, which, of course, if ever invoked will come back to bite the Democrats big time, if and when Republicans ever control the Senate again. [emphasis added to quotes]
