Leadership changes in England that effects Americans:
For a long period of time, America was the colony of the Britishers until it started to oppose and take revolutionary movements against people in England and any move in England had a direct impact on America because it could change the way England would govern it's colonies.
If the leaders in England change, it could change the way colonies are treated by either being a little lenient or being even more harsh depending up on the leader in power.
