This is why betting 130k dollars on either Biden or Trump would be something silly to do, why risk so much money when you do not know who would be the favorite of the people? Only logical answer could be having tens of millions of dollars and doing this for fun.
This is why many bettors are betting big money on Trump since he has succeeded as an underdog in the past. I feel it's 50-50 at this point between Trump and Biden.
Also see that on the past election and though Clinton would win against trump but things change so I wonder if trump will do it again for the second time since Biden is so strong these days base on the poll, but we cannot really say who's the winner based on that since the result will really change depends on how the candidate campaign his self on the last minute of campaign period.
Clinton is not Biden so don't be so sure since the result sometimes will not the same although trump got a good chances but Biden is not easy to be beaten since he's a strong candidate which have many supporters. This election is 50-50 chances between them.
