"Other than the POTUS" seems to brazenly ignore the significance. For example, it would be absurd to ask, 'When Trump took office, what changed from Obama other than the POTUS'?
When Obama took office, the new POTUS' policies aligned to a significant degree with the anti-war protestors. Obama had opposed the Iraq war from the start and promised to withdraw, which he did (though the withdrawal was also required by the agreement Bush made with Iraq). Obama also wanted out of Afghanistan and, after a policy review, set a timeline for it (a criticized decision that was later changed).
> both sides are wrong
This is true "political correctness" (a term that I think is almost always misused). The odds of both sides begin equivalent seem slim; it's not at all unlikely that of two parties, one would be significantly worse than the other. It's sort of like looking at two software programs and saying 'both have bugs'; sure, but that's meaningless - it's not at all surprising when one is much superior to the other.
But people like to be even-handed, out of some misguided (IMHO) view of fairness or not wanting to offend. But the stakes are too high; you wouldn't say that if you were choosing between airplane autopilot programs. In this case, if you make the worse choice then it can result in catastrophic climate change, nuclear proliferation, war, mass oppression, the undermining of democracy and liberty, and more.
