He Gambled against Biden.
He had high wagers apparently against him.
He did not have any plan B.
Now Hungary is not a Fan of Biden for sure but the funniest thing is , these were the words of the Hungarian President after loosing the bet :
At least he wasn't a sore looser. How many of you guys did bet against Trump ? Did anyone loose a critical amount ? What are your thoughts on this particular thing ?

He knows how to move forward after he lost the bet and he cannot do anything but to make peace with the President of the strongest nation in the world he is the President of Hungary and he represents the people and he needs to move forward and make peace for the sake of diplomatic relations of both countries, but honestly, it's a bad decision to come out openly about his disliked to Biden it might put his party in peril if your country has a good relationship with America you should have an independent view on their election and not put loyalty on one candidate.
