The problem is that the US has difficulty operating as a modern democracy in general.
Yeah sure, I agree with you that proclamations and executive orders are inherently vulnerable to the whims of whomever happens to hold the office and have no place in a democracy.
But the legislative branch, as it currently operates, is not much different. In practice it results in huge pendulum swings and deadlocks, making every 2 years (because midterms) a nail biting event for the populous because hard fought rights and legislation can be undone in the blink of an eye.
As someone who grew up in a coalition country, it’s saddening to see how people around me here in the US are constantly in a state of anxiety, filled with despair like someone who’s awaiting the return of an abusive spouse from work, wondering what will happen this time.
If we somehow could get rid of the FPTP system in our legislative system, then we can rid ourselves from the two party system.
Not only will this significantly lessen things like gerrymandering, and the power of lobbying, but it would force parties to form a coalition because it’s less likely that one single party holds the majority of seats.
Parties would have to actually debate each other and try to convince each other, make concessions on all sides, in order to form a coalition.
The result of this is a more steady course in government policy, with sweeping pendulum swings being rarer and the changes being made being more nuanced.
Subsequently the citizenry doesn’t have to be on high alert 24/7 and the country can function more like a modern democracy.
And next thing in the agenda would be judicial reform.
Until then, both the legislative branch and the executive branch will subject us to whims and other pendulum swings.
