Reality is complex and dynamic, and through all of that Harvard's endurance pre-dates the US, therefore I would expect it to endure a 4 year term of Government. Not to say with a 100% certainty, but I would expect it to with a greater degree of confidence than many other things, based on its history.
However I wouldn't extend that line of thinking to stock markets, superannuation etc.
I worked for a foundry that had been at the same location for 120 years. GE ran it into the ground and closed it 2 years after acquiring it.
