I beg to differ for a few reasons and I have a different argument to boot.
- If you shift to national popular vote, those millionsof Californian Republicans suddenly count. The "Republican" parts of California, those 6 districts are biggerthat Wyoming and of course, more populous. Same for the millions of Democrat Texans.
- 70% of the geographic area of the USA is alreadyelectorally irrelevant because it belongs to states that we all know what they will vote. Only battleground states count.
- "Rural" USA is not 90% of USA's geographical area. USA's mean pop density is 87/sq.mile. As you can see from this map, even if we consider "irrelevant" states that have less than 50/sq.mile the total is less than 50% of USA's geographical area.
As such, under the current system 70% of USA is already electorally irrelevant while popular vote would improve that to 40% electorally irrelevant. And let's not forget the senate that goes strictly by state.
And the different argument:
Those rural folks that live in the 40% of rural USA? They are too few. There is an argument to be made that they shouldbe irrelevant compared to the vast majority that lives in other states.
To put it simply: If 60% of the people of USA live in Minnesota, the 40% of the people that live in the 98% of the geographic area of USA should be beholden to that large majority that lives in Minnesota. The 40% of non-Minessotans should not dictate the POTUS despite living in many empty states.
I am not 100% pro that though; As I said, there should be adjustment, but lighter.
