The arguments in favor of this are simply unconstitutional. Nowhere in the constitution does it say a president shouldn't appoint a justice during her or his last year. Period! This is Republican obstructionism at its best. They are just upset that they are losing one of their most important and influential justices. The Democrats felt the same way when Thurgood Marshall died, but his seat was filled by Clarence Thomas. I'm tired of hearing we should wait for the next election and let the voters decide. The voters did decide, twice. Barack Obama is the president and has the constitutional authority to make nominations. If the Republicans refuse to do their job, they are basically holding one of the three branches of government hostage.
