Update: Equation of States for US Presidential Elections

I modified the figure a little bit to show the two forbidden regions in the 2nd and 4th quadrants, which are violated twice in the past US presidential elections now.

Update: Equation of States for US Presidential Elections

Updated with the newest data, Clinton 59,835,153 votes (228), Trump: 59,618,815 votes (279), from USA today. Like the 2000 election, the result this time fell again in the forbidden regions, the 2nd and 4th quadrants. The people of US should consider a new electoral system.

I made a bead model for the zeolite PKU-12 and gave it to the chemistry college of Peking University as a souvenir when I was invited to Beijing last November.
