The state isn't voting homogenously. Just like Eastern Washington could vote differently to the Puget Sound with more direct representation.
The key word in your argument is 'populous'. Thinking in terms other than people, be it states/counties/acreage is another version of putting "landowners" in charge.
> Why people leaving in LAC should be in virtually full control (with the current power of federal government it's very close to that)
Which explains why politicians spend so much time in Election season in LAC. Except they don't. They are instead in Ohio, Montana, NH, Wyoming, Iowa, Florida.
Again, having 3 votes against 57 does not put whoever has 3 votes "in charge" in any sensible meaning of the word.
> Except they don't.
Because they think LAC has already made up their minds, no matter what. And judging from voting patterns, they are correct. So whose fault is that? If more LAC voters would vote diversely, politicians would pay more attention to LAC, they are not stupid. But when it's 70+% to one side, why bother? Same campaigning dollar would bring much more impact elsewhere, and campaign resources are finite.
LAC and NYC both voted very blue, yet here we are. How do you credibly claim that "LAC is by and large in charge of the direction of the federal government"?
Claiming that because California has 57 votes and Wyoming a whopping 3 votes, instead of California having 70 and Wyoming one (if at all), we "no longer have representative democracy" is nonsense. California still have wastly more votes. Yes, Wyoming also gets some, otherwise it why bother voting at all if everything is essentially decided by the most populous states anyway?
> protection results in a tyranny of the minority
3 votes against 57 is hardly "tyranny".
> Why are the concerns of the people living in LAC less important than the concerns of the people in Nevada or Arkansas?
Why people leaving in LAC should be in virtually full control (with the current power of federal government it's very close to that) over people of Nevada and Arkansas and Wyoming? What's the point for Wyoming to sign up for such a deal to be ruled by LAC?
