There have been great debates about the direction of the country already, but new ideas come primarily from the left as the right wants to bring back what it has been tried before, often with dire outcomes. Yes, "the system" has a momentum that can't be easily changed given present political realities, unless, as Bernie Sanders says, public opinion and voting changes to reflect the need for change--change that will restore most benefits to the middle class.
The presidential term lasts 8 years, and Obama has over 300 days left in office. God just gave us a gift by recalling Scalia from the US Supreme Court. How can you argue with God, right? Scripture, as per St. Paul, says the people should obey those in power, because, after all, there's a divine plan in place. Therefore, Obama should nominate a replacement asap, and the president should be the communicator-in chief in order to get the new SCOTUS justice confirmed by the Senate.
Despite the nice statements about the departed justice, Scalia was a divisive figure and a conservative champion who believed in a romantic but unrealistic view of the US constitution. The conservatives have been attacking the liberal justices as "activists" who find rights in the constitution and overturn the "will of the people" and legislatures. Of course, the 2000 SCOTUS decision to essentially give G.W. Bush the presidency was an act of judicial activism by the conservatives, though they tend to forget it.
Marco Rubio put it bluntly yesterday, that the US constitution is not "a living, breathing" document but must be interpreted "as the founders intended." This is a conservative but misguided view. The constitution was meant for a living and breathing country, not a dead one of the 18th century..... a time when owning arms meant a musket and a knife! Indeed, we tweaked the constitution 27 times already.
Also, many necessary changes that promoted rights, freedom, and the quality of life came via the judiciary branch, especially when some states--often representing local majorities--remained stuck in the 18th century conservatives seemed to love. Oh, yeah, there are "moderate conservatives" I hear. OK, it's true. These are the ones who love the time before the New Deal. Maybe that's what Trump means by "Let's Make America Great Again."
There are many cases of importance the high court has to decide before it goes into recess in June, cases such for voting rights, Obamacare, union organizing, immigration, etc. So, let the gladiatorial games begin... Happy Chinese new year by the way.
