Everyone else is focusing on whether the rest of the world uses metric and not that fact that water pressure at a given faucet or shower head will be governed by bernoullis equation which will take 99 things into account such as:
The max height of the water reservoir
The height of your faucet
The design of the pipes leading from the reservoir to your faucet
Air pressure
The pumps in the system
Etc
Doubtful. Clinton wouldn’t have focused on division. Sure, it would have simmered like during Obama’s years. But you can name 99 polarizing things Trump did and I can think of few Clinton would have done. Besides, you know, being a woman and continuing Obama’s legacy.
