誰會贏得總統大選?

(2020-10-11 10:34:19) 下一個
Yahoo news has an articles from Insider Monkey about how to count each state votes towards Trump and Biden. The conclusion is that Trump has much larger chance to win than polls number suggests. 
 
https://finance.yahoo.com/news/win-presidency-001318552.html
 
I am making three points here: 
1. The articles does not count the votes correctly, which is a low-level error. 
2. The article count most of battlegound states towards Trump. 
3. Even with all counting from the article, winning Pennsyvania will give both side win, but it has been predicted by Fivethirtyeight to Biden win with 6.3 points difference. 
 
First counting the votes correct:
Hawaii has 4 electoral votes, instead of 3, to biden
Maine has 4 electoral votes, instead of 3, to biden
Texas has 38 electoral votes, instead of 36, to trump
Washington has 12 eletoral votes, instead of 8, to biden
 
From Trump: 258 – Biden:253, change to 
Overall : Trump: 260 – Biden:259  + 20 (PA no attribution) = 538, which is correct number. 
 
 
The battleground states: Fivethirtyeight 2020 predicts Trump loss, but Insider Monkey can predict either Trump win or loss. 
 
Florida: Fivethirtyeight 2020 prediction: Trump loses by 3.6 points; Insider Monkey Prediction: Trump wins by 1 vote. Trump wins, 29 votes here. 
Georgia: Fivethirtyeight 2020 prediction: Trump loses by 0.7 points; Insider Monkey Prediction: Trump wins by 1.1+ points. Trump wins, 16 votes here. (according to the different prediction direction of insidermonkey and fivethirtyeight)
Iowa: Fivethirtyeight 2020 prediction: Trump loses by 1 point; Insider Monkey Prediction: Trump wins by 7.1 points. Trump wins, 6 votes here. 
Michigan: Fivethirtyeight 2020 prediction: Trump loses by 8.3 points; Insider Monkey Prediction: Trump loses by 2.6 points. Trump loss, 16 votes here. 
Minnesota: Fivethirtyeight 2020 prediction: Trump loses by 8.2 points; Insider Monkey Prediction: Trump loses by 1.5 points. Trump loss, 10 votes here. 
North Carolina: Fivethirtyeight 2020 prediction: Trump loses by 1.9 points; Insider Monkey Prediction: Trump wins by 1.8 points. Trump win, 15 votes here. 
Ohio: Fivethirtyeight 2020 prediction: Trump loses by 0.5 points; Insider Monkey Prediction: Trump wins by 5.7 points, Trump win, 18 votes here. 
Pennsylvania: Fivethirtyeight 2020 prediction: Trump loses by 6.3 points; Insider Monkey Prediction: Trump wins/loses by 0.0 points, 20 votes here. 
Wisconsin: Fivet Fivethirtyeight 2020 prediction: Trump loses by 6.4 points; Insider Monkey Prediction: Trump loses by 0.6 points, Trump loss, 10 votes here. 
 
overall votes from battlegrounds states: 140 votes, where Insider Monkey counts Florida, Geogia, Iowa, North Carolina, Ohio towards Trump, which has overall 84 votes, counts Michigan, Minnesota, Wisconsin towards Biden, which has 36 votes. 
 
Remove all the votes from the battleground states, it becomes:
Trump: 176 – Biden:223.
