Anthony Kennedy is retiring. I suspect Trump will select a "conservative" judge as the Democrats seem to point out, and the funny thing is is that the Constitution of the United States is a conservative document by its nature and by the nature of those who wrote it. After the travel ban ruling, which I find Constitutionally legal and absolutely necessary, this is another great step forward to ending the regression our country has had and hopefully prevents us from making the same mistake with irresponsible mass refugee admissions or illegal alien amnesties that have plagued the EU. 

It should be noted I'm unaware of whether the EU has granted amnesties to illegal border crossers or not, I'm more connecting the refugees and illegals as similar problems EU countries and the United States currently confront.
