Initial reaction, and plenty of important questions.
The death of Antonin Scalia will surely create endless Obama-Congress disputes when Obama will present his new choice(s). Also, many cases are to be decided during the elections cycle of 2016 and having 8 judges on board, with one less very conservative judge will make the decisions very close or tied or unforeseen postponements.
It will not be good for Congress, as it will show the American people and the world how even in jurisprudence, the American way is all about politics and personal tendencies instead of the true application of the law.
The Republican debates now will have the added feature of gay marriage at the top of the agenda and Trump is most likely to say stupid things and tweet ridiculous idea that will expose even further the bigotry and racism that are latent in the United States.
