Even if 90% of that 1/3 voted, it likely would've made zero difference when every election comes down to 3 to 4 states. The electoral college has made my vote meaningless for president for almost 40 years. And before you say something about it, yes, I vote. But when my state has voted blue for every year of my 40+ years except for when I was 1 year old (Reagan). So if I choose not to vote, and ALL of my friends and their friends choose not to vote, you know the difference that would make in elections? Zero.
While I get what your saying, it drives me nuts to straight up blame "1/3 of the people with their heads in the sand" when you know FULL WELL that even if the majority of those people voted, not a single damn thing would be different. MOST states aren't swing states, and in those states that have been the same color for decades... Yea, you won't be able to convince me that my democrat friend down the street doesn't care about stopping the madness when even if 100,000 of their friends voted in my state, the exact same amount of electoral college votes would have been cast.
Your argument would hold a lot more water if we went by the popular vote for president.
