I already played with growing the Electoral College by implementing the "Wyoming Rule" in regards to allotting seats in the US House of Representatives. The outcome still came out in favor of Trump, with an even larger Electoral Margin at that--thanks in large part to Michigan and Pennsylvania. So that wouldn't have resolved the issue of "the electoral president" by itself.
Since this was the second election in the last five where the candidate who won the popular vote failed to win the electoral mandate, I'm beginning to think the EC has outlived its usefulness. Time for the popular vote to elect the President, as it does every other office.
If Instant Runoff had been used to ensure a popular majority in each state before WTA applies, we have this as a potential quick run down:
No change: AK, WA, OR, CA, HI, ID, MT, WY, ND, SD, NE, KS, OK, TX, LA, AR, MO, IA, IL, IN, KY, TN, MS, AL, NC, WV, OH, SC, GA, DC, MD, NJ, NY, DE, CT, MA, VT, RI.
So 37 states plus DC had a clear popular majority, no instant runoff needed.
Which leaves 13 for "Instant runoff" to break 50%. I'll presume Green party votes would go to Hillary, while Libertarian and McMullin votes go for Trump.
Nevada: outcome unclear, at least using CNN's polling data, unable to get to 50%+1 of the vote. Information from Fox News doesn't help.
Utah: Remains Trump.
Arizona remains Trump.
New Mexico: Unclear with CNN's polling data, can't break 50%. Fox News Data puts Trump at 50% in theory... (Trump 40.0%, Johnson 9.3%, McMullin 0.7%)
Colorado: Unclear with CNN's polling data, can't break 50%. Fox News Data flips it to Trump. (Trump 44.4%, Johnson 5.0%, McMullin 1%; netting 50.4%)
Minnesota: Unclear with CNN's polling data, can't break 50%. Fox News Data flips it to Trump. (Trump 45.4%, Johnson 4.9%, McMullin 1.8%; netting 52.1%)
Wisconsin: Unclear with CNN's polling data, can't break 50%.Fox News data keeps it with Trump. (Trump 47.9%, Johnson 3.6%; netting 51.5%)
Virginia: Remains Clinton
Florida: remains Trump
Michigan: Goes Trump (considered tossup still)
Pennsylvania: Remains Trump
New Hampshire: Goes Trump (flips current result)
Maine: Goes Trump (flips result, unclear as to outcome on the district level. Would shift at least 2 EC votes to Trump, possibly 3)
And of course, we have the "raw" popular vote nationwide:
Hillary Clinton 60.1 Million (rounded up), 59.8 Million(rounded down), Johnson 4.1 Million(rounded up), Stein(Green party) 1.2 Million(rounded down), McMullin 0.4 Million(rounded down)
59.8+4.1+0.4= 64.3 Million votes for "conservative" options.
60.1+1.2= 61.3 Million votes for "liberal" options.
