Britain's decision to leave the EU provided the spark for the second Scottish referendum. Scottish voters decided in a 2014 referendum that they wanted to keep their ties to the U.K. rather than become an independent country. There are so many variables that it's not at all clear how quickly an independent Scotland could become part of the EU. If Britain seems to be getting a good economic deal with many benefits, Scottish voters may decide — again — to stay put. But if the deal seems overly harsh, Scottish voters may feel they have little to lose by opting out.
