It really matters which party runs economy

This is really interesting that when republicans holds the Oval Office, US Dollar has been weakened by them..! In contrast, when ever democrats hold the office their decisions result in stronger US dollar!
You may assume it is a coincidence, but it has been repeated in the last 36 years!
Based on the chart, Donald Trump will win the election one more time, Dollar will sink, and Gold will soar..!
