Pres Obama has already had 2 new Supreme Court Justices confirmed - in 2009 & 2010 so the Senate has an idea of what type of Justice he would nominate. We need to make sure we get another Justice that doesn't want to make laws, or interpret them to placate certain parts of society. We need a Justice that will put our religious liberties before our government. Ex: Little Sisters of the Poor and others are constantly having to go to court to defend their religious freedom. The court hasn't backed them up yet - it should be unanimous. We need to have someone that will fight and defend our freedoms given in the constitution. The Senate can determine how many Justices there are - they can add or take away the number of Supreme Court justices.
