Metric / Imperial - trivialities. Especially in the era of ubiquitous pocket computers, why does this even come up in discussion? (I personally like the random fact that miles to km is really close to the golden ratio...)
Regarding electoral college: you can pry that from my (and may others') cold dead fingers. The electoral college, flawed as it may be, protects us against tyranny of the majority, which is still by far a worse situation than tyranny of a minority. I do not want to live in a situation where either CA or TX or FL or NY can basically decide the direction of the country.
Until we fix the balances of power and the Senate specifically gets its act together, there is no way I would want such a thing to happen.
I have no hope of seeing the Electoral College removed anytime soon. I also don't see the justice of it. I've previously shown the math on how voters in low-population states have much more voting power
per person due to minimum-representation in the House and EC, not to mention the Senate. The Senate was explicitly designed to mitigate the will of the people, the others are more subtle and seemingly accidental.
It's like if a vote for Student Body President was done by polling each club at a school, giving each club a minimum of three votes for some reason. Somehow this is supposed to prevent the biggest clubs from dominating the smaller ones... but how does forcing the clubs to vote as blocs do that? (and then some clubs choose to split their votes anyway?!)
And then a bunch of bright individuals create their own one-person clubs which still get the minimum three votes. They tend to vote together in most ways, wielding great voting power, while constantly wringing their hands about how small each of their "clubs" is. The big math club gets 20 votes, while the 10 of them only get 3 each! It's *so unfair*. The evil math club must be resisted!
And then on policy issues every single one of them has exactly as much voting power as the entire math club (The Senate). But this is okay because it's on purpose. Clubs are literally more important than students - that's explicitly the design goal.
Populism is an actual concern, which is why I don't generally complain about the Senate (just the House and EC). But the EC is not remotely fair to anyone involved, really, and I fail to see what purpose it serves. Our votes go through a pachinko machine, and we wonder why voters feel helpless and dissatisfied... even distrustful of their representation. It all feels like a con job, and in a way it literally *is*. Again, the Senate exists to resist popular opinion. I just don't think the framers foresaw California and North Dakota interacting in the same union.
