2016 Deaths, Revisited
Castro's death will change our foreign policy. While Cuba might seem like a minor country, it was a big deal that President Obama opened up travel and trade with the country.
Scalia is a different matter. I would argue that Donald Trump would not be president if Scalia had lived. The one argument bought by millions of conservative voters who were totally unimpressed by Trump was that he would replace Scalia with a constitutionalist. If Scalia was around and kicking, the urgency would not have been as real.
